Ingredients

• Cauliflower Florets: (About 6 cups) The star of the show! Fresh cauliflower provides a healthy, low-carb base and a mild flavor that complements the cheesy sauce. You can also use frozen cauliflower florets, just ensure they are thawed and drained well to avoid excess moisture in your casserole.
• Cooked Chicken Breast: (2 cups, shredded or diced) Provides lean protein and a satisfying heartiness to the casserole. You can use leftover rotisserie chicken, grilled chicken, or bake or poach chicken breasts specifically for this recipe.
• Shredded Cheddar Cheese: (2 cups) The classic cheese for casseroles! Cheddar offers a sharp, savory flavor and melts beautifully, creating that irresistible cheesy pull. Use a good quality cheddar for the best taste.
• Shredded Monterey Jack Cheese: (1 cup) Adds a creamy, mild flavor and excellent melting properties, contributing to the overall gooeyness of the casserole. Monterey Jack also helps to balance the sharpness of the cheddar.
• Heavy Cream: (1 cup) The secret to the rich and decadent sauce! Heavy cream provides a luxurious creaminess and helps to bind all the ingredients together.
• Milk: (1/2 cup) Thins out the heavy cream slightly to create the perfect sauce consistency without making it too heavy. You can use whole milk, 2%, or even skim milk, though whole milk will provide the richest flavor.
• Cream Cheese: (4 ounces, softened) Adds tanginess and extra creaminess to the sauce. Softened cream cheese blends seamlessly into the sauce and creates a velvety texture.
• Butter: (2 tablespoons) Used to sauté the aromatics and adds richness to the sauce base. Butter also helps to develop flavor in the initial stages of cooking.
• All-Purpose Flour: (2 tablespoons) Acts as a thickening agent for the sauce, ensuring it’s not too thin and coats the chicken and cauliflower beautifully.
• Garlic: (2 cloves, minced) Essential for adding savory depth and aroma to the casserole. Freshly minced garlic is always best, but you can use garlic powder in a pinch.
• Onion: (1/2 cup, diced) Another aromatic that builds a flavorful base for the sauce. Diced onion adds a subtle sweetness and savory note.
• Dried Thyme: (1 teaspoon) Adds a subtle earthy and herbaceous note that complements the chicken and cheese flavors beautifully. Dried thyme is a classic pairing for creamy casseroles.
• Salt: (To taste) Enhances all the flavors in the casserole. Season generously but taste as you go to avoid over-salting.
• Black Pepper: (To taste) Adds a touch of spice and complexity. Freshly ground black pepper is preferred for its brighter flavor.
• Optional Topping: Breadcrumbs: (1/2 cup, Panko or regular) Adds a delightful crunchy texture to the top of the casserole. Panko breadcrumbs are particularly good for a crispy topping. You can also use crushed crackers or even shredded cheese for the topping.
• Optional Topping: Fresh Parsley: (For garnish, chopped) Adds a pop of freshness and color to the finished casserole. Fresh parsley brightens up the dish visually and adds a subtle herbaceous flavor.

Instructions

1. Preheat Your Oven and Prepare the Cauliflower: Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish. If using fresh cauliflower, wash it and cut it into bite-sized florets. If using frozen cauliflower, thaw it completely and squeeze out any excess water.
2. Cook the Cauliflower: There are a few ways to cook your cauliflower. For a slightly firmer texture, you can steam or boil the cauliflower florets until they are tender-crisp, about 5-7 minutes. Alternatively, for a roasted flavor, toss the cauliflower with a tablespoon of olive oil, salt, and pepper, and roast at 400°F (200°C) for 15-20 minutes until slightly tender and lightly browned. Roasting adds a deeper flavor dimension to the casserole. You can also microwave the cauliflower florets with a little water until they are tender-crisp if you are short on time. Do not overcook the cauliflower at this stage as it will continue to cook in the casserole.
3. Sauté Aromatics: In a large skillet or pot, melt the butter over medium heat. Add the diced onion and cook until softened and translucent, about 5 minutes. Add the minced garlic and cook for another minute until fragrant, being careful not to burn the garlic. The aroma should be enticing and savory.
4. Make the Cream Sauce: Sprinkle the flour over the sautéed onions and garlic and cook for 1-2 minutes, stirring constantly, to create a roux. This will help thicken the sauce. Gradually whisk in the milk and heavy cream, stirring continuously to prevent lumps from forming. Continue to whisk until the sauce is smooth.
5. Add Cheese and Seasoning: Reduce the heat to low. Add the softened cream cheese, cheddar cheese, and Monterey Jack cheese to the sauce. Stir until all the cheese is melted and the sauce is smooth and creamy. Season with dried thyme, salt, and black pepper to taste. Adjust seasoning according to your preference. Taste the sauce and make sure it is well-seasoned, as this is the flavor base of the casserole.
6. Combine Ingredients: Add the cooked chicken and cooked cauliflower florets to the cheese sauce. Gently stir to combine everything, ensuring the chicken and cauliflower are evenly coated in the creamy sauce.
7. Assemble the Casserole: Pour the chicken and cauliflower mixture into the prepared baking dish, spreading it out evenly.
8. Add Topping (Optional): If using breadcrumbs, sprinkle them evenly over the top of the casserole. You can also drizzle a little melted butter over the breadcrumbs for extra browning and flavor. Alternatively, you can sprinkle extra shredded cheddar cheese or a combination of cheeses on top for an extra cheesy crust.
9. Bake the Casserole: Bake in the preheated oven for 20-25 minutes, or until the casserole is bubbly and heated through, and the topping (if using) is golden brown and crispy. The cheese should be melted and gooey, and the casserole should be heated to an internal temperature of 165°F (74°C).
10. Rest and Serve: Let the casserole rest for 5-10 minutes before serving. This allows the sauce to thicken slightly and the flavors to meld together. Garnish with fresh parsley, if desired, before serving. Serve hot and enjoy!

How to Serve

This Cheesy Chicken and Cauliflower Casserole is a complete meal in itself, but it pairs wonderfully with a variety of side dishes to create a more balanced and satisfying dining experience. Here are some serving suggestions:

• Fresh Green Salad: A simple green salad with a light vinaigrette dressing provides a refreshing contrast to the richness of the casserole. The crispness of the salad and the acidity of the dressing cut through the creaminess and add a welcome lightness to the meal. Consider adding mixed greens, cucumber, tomatoes, and a lemon vinaigrette.
• Roasted Vegetables: Roasted vegetables like broccoli, asparagus, Brussels sprouts, or green beans complement the casserole beautifully. Roasting brings out the natural sweetness of the vegetables and adds a different texture dimension. Toss vegetables with olive oil, salt, pepper, and herbs like rosemary or thyme before roasting.
• Garlic Bread or Dinner Rolls: For those who love to soak up every last bit of the delicious cheese sauce, garlic bread or warm dinner rolls are a must-have side. Homemade garlic bread or crusty dinner rolls are particularly delightful.
• Steamed Green Beans or Broccoli: A simple side of steamed green beans or broccoli adds a healthy and vibrant green element to the plate. Lightly season with salt, pepper, and a squeeze of lemon juice.
• Tomato Soup: A warm bowl of tomato soup before the casserole is a classic comfort food pairing. The acidity of the tomato soup complements the richness of the casserole.
• Mashed Potatoes or Sweet Potatoes: For an extra hearty meal, serve the casserole alongside a scoop of mashed potatoes or mashed sweet potatoes. This combination is particularly comforting on a cold evening.
• Quinoa or Rice: If you prefer a grain-based side, quinoa or rice are good options. They provide a neutral base that absorbs the flavors of the casserole.
• Coleslaw: A creamy coleslaw can provide a cool and crunchy contrast to the warm and cheesy casserole, especially during warmer months.

Serving Garnishes:

• Fresh Parsley or Chives: Sprinkle chopped fresh parsley or chives over the casserole before serving for a pop of color and freshness.
• Paprika: A dusting of paprika adds a subtle smoky flavor and visual appeal.
• Crushed Red Pepper Flakes: For those who like a little heat, a sprinkle of crushed red pepper flakes adds a spicy kick.

Additional Tips for the Best Cheesy Chicken and Cauliflower Casserole

1. Don’t Overcook the Cauliflower: Whether you choose to steam, boil, roast, or microwave your cauliflower, be sure to cook it until it’s just tender-crisp. Overcooked cauliflower will become mushy in the casserole, affecting the texture. It should still have a slight bite to it before being added to the sauce.
2. Use Good Quality Cheese: The quality of your cheese directly impacts the flavor of the casserole. Use good quality cheddar and Monterey Jack cheese for the best taste and melting properties. Freshly grated cheese melts more smoothly than pre-shredded cheese, which often contains cellulose to prevent clumping.
3. Season Generously: Don’t be shy with seasoning! Taste the sauce before adding the chicken and cauliflower and adjust the salt, pepper, and thyme as needed. Proper seasoning is key to bringing out all the delicious flavors in the casserole.
4. Make it Ahead of Time: You can assemble the casserole ahead of time and store it, unbaked, in the refrigerator for up to 24 hours. When ready to bake, add about 10-15 minutes to the baking time to ensure it is heated through. This makes it a great option for potlucks or busy days.
5. Add a Crunchy Topping: While optional, a crunchy topping like breadcrumbs, crushed crackers, or even fried onions adds a delightful textural contrast to the creamy casserole. Panko breadcrumbs are particularly good for a crispy topping.
6. Customize Your Cheese: Feel free to experiment with different types of cheese! Gruyere, Fontina, Pepper Jack, or a blend of Italian cheeses would all work well in this casserole. Consider using a combination of cheeses for a more complex flavor profile.
7. Add Vegetables: Want to sneak in more vegetables? Feel free to add other cooked vegetables to the casserole along with the cauliflower. Roasted broccoli, peas, carrots, or mushrooms would all be delicious additions. Just ensure they are cooked before adding them to the casserole.
8. Control the Creaminess: If you prefer a slightly lighter casserole, you can substitute half-and-half or even milk for some of the heavy cream. However, keep in mind that this will result in a less rich and creamy sauce. For the most decadent and flavorful result, stick with heavy cream as indicated in the recipe.

Frequently Asked Questions (FAQ) about Cheesy Chicken and Cauliflower Casserole

Q1: Can I use frozen cauliflower for this recipe?

A: Yes, you absolutely can use frozen cauliflower! Just make sure to thaw it completely and drain it very well before adding it to the casserole. Frozen cauliflower tends to retain more water than fresh, so squeezing out the excess moisture is crucial to prevent a watery casserole.

Q2: Can I substitute the chicken with something else?

A: Yes, you can substitute the chicken with other cooked proteins. Shredded turkey, ham, or even cooked ground beef or sausage would work well. For a vegetarian option, you could use cannellini beans or chickpeas for added protein and texture. You could also simply omit the chicken entirely for a cheesy cauliflower casserole.

Q3: Can I make this casserole vegetarian?

A: Yes, to make this casserole vegetarian, simply omit the chicken. The cheesy cauliflower base is delicious on its own! You can also add other vegetables like sautéed mushrooms, spinach, or bell peppers to make it even heartier and more flavorful.

Q4: Can I make this casserole gluten-free?

A: Yes, you can easily make this casserole gluten-free. Ensure all your ingredients are gluten-free. Substitute the all-purpose flour with a gluten-free all-purpose flour blend or cornstarch to thicken the sauce. For the topping, use gluten-free breadcrumbs or crushed gluten-free crackers, or simply omit the topping altogether.

Q5: How long does Cheesy Chicken and Cauliflower Casserole last in the refrigerator?

A: Properly stored in an airtight container in the refrigerator, leftover Cheesy Chicken and Cauliflower Casserole will last for 3-4 days. Ensure it cools down to room temperature before refrigerating it.

Q6: Can I freeze Cheesy Chicken and Cauliflower Casserole?

A: Yes, you can freeze this casserole, although the texture of the cauliflower and sauce may change slightly upon thawing and reheating. For best results, freeze the casserole before baking. Assemble the casserole in a freezer-safe dish, cover tightly with plastic wrap and then aluminum foil, and freeze for up to 2-3 months. To bake from frozen, thaw overnight in the refrigerator and then bake as directed, adding extra baking time as needed. You can also bake it directly from frozen, but it will take significantly longer to cook through.

Q7: I don’t have heavy cream, what can I use instead?

A: If you don’t have heavy cream, you can substitute it with half-and-half or evaporated milk. Half-and-half will provide a slightly less rich sauce, and evaporated milk will result in a thinner sauce. For a richer substitute, you can try using crème fraîche or full-fat coconut milk (for a slightly different flavor profile).

Q8: Can I add other spices or herbs to this casserole?

A: Absolutely! Feel free to customize the flavor profile by adding other spices and herbs to your liking. Nutmeg, paprika, onion powder, garlic powder (if not using fresh), rosemary, or Italian seasoning would all be delicious additions. Experiment and find your favorite flavor combinations!
