Easy Low Carb Chicken Casserole With Turkey Bacon
Prepare a creamy chicken casserole with turkey bacon and vegetables.
Ingredients
- Main Casserole:
- 2 lbs (900g) boneless, skinless chicken breasts, cooked and shredded
- 8 slices (225g) turkey bacon, cooked crisp and crumbled
- 4 cups (400g) broccoli florets, fresh or frozen, thawed and drained
- 4 cups (400g) cauliflower florets, fresh or frozen, thawed and drained
- 1 tbsp (15ml) olive oil, or reserved bacon fat
- 1 medium yellow onion, finely diced
- 3 large cloves garlic, minced
- 8 oz (225g) full-fat cream cheese, softened
- 1 cup (240ml) heavy cream
- ½ cup (120ml) low-sodium chicken broth
- 1 tsp (5g) fine sea salt
- ½ tsp (2.5g) fresh ground black pepper
- ½ tsp (2.5g) dried thyme
- ¼ tsp (1g) red pepper flakes, optional
- Cheese Topping:
- 2 cups (200g) sharp cheddar cheese, shredded
- 1 cup (100g) whole milk mozzarella cheese, shredded
- For Garnish (Optional):
- 2 tbsp (10g) fresh parsley, chopped
Instructions
- Preheat oven to 375°F (190°C). Cook 8 slices (225g) turkey bacon in a large oven-safe skillet or frying pan over medium heat for 8-10 minutes, flipping occasionally, until crisp and golden brown. Remove bacon, drain on paper towels, and crumble when cooled. Set aside 4 slices (112.5g) crumbled bacon for topping. Reserve the remaining 4 slices (112.5g) for the casserole mixture.
- Use the oven-safe skillet or a large pot. Add 1 tbsp (15ml) olive oil (or 1 tbsp reserved bacon fat) to the skillet over medium heat. Sauté 1 medium diced yellow onion for 3-5 minutes, stirring frequently, until soft and translucent. Stir in 3 minced garlic cloves and cook for 1 minute, stirring constantly, until fragrant and lightly golden.
- Steam or blanch 4 cups (400g) fresh broccoli florets and 4 cups (400g) fresh cauliflower florets in boiling water for 3-5 minutes until crisp-tender. Drain thoroughly and pat dry. If using frozen vegetables, ensure they are thawed and squeezed dry to prevent a watery casserole.
- Reduce heat to low. Add 8 oz (225g) softened cream cheese to the skillet with aromatics. Stir continuously for 2-3 minutes, pressing against the pan bottom, until fully melted and smooth. Gradually whisk in 1 cup (240ml) heavy cream and ½ cup (120ml) low-sodium chicken broth, stirring for 2-3 minutes until slightly thickened and smooth.
- Remove skillet from heat. Stir in 1 tsp (5g) fine sea salt, ½ tsp (2.5g) fresh ground black pepper, ½ tsp (2.5g) dried thyme, and ¼ tsp (1g) red pepper flakes (if using) into the sauce. Taste and adjust seasonings as needed.
- In a large mixing bowl, combine 2 lbs (900g) cooked, shredded chicken, prepared broccoli and cauliflower florets, 4 slices (112.5g) crumbled turkey bacon (reserved from Step 1), 1.5 cups (150g) shredded sharp cheddar cheese, and 0.5 cup (50g) shredded whole milk mozzarella cheese. Pour the creamy sauce over the mixture. Gently fold all ingredients together for 1-2 minutes until thoroughly coated and evenly distributed.
- Transfer the chicken and vegetable mixture into a 9×13 inch (23×33 cm) baking dish. Spread evenly to create a consistent layer.
- Evenly sprinkle the remaining 0.5 cup (50g) shredded sharp cheddar cheese and 0.5 cup (50g) shredded whole milk mozzarella cheese over the casserole. Scatter the remaining 4 slices (112.5g) crumbled turkey bacon (reserved from Step 1) over the cheese. Bake in the preheated oven at 375°F (190°C) for 25-30 minutes, until cheese is fully melted, bubbly, and edges are lightly golden brown.
- Optional: For an extra golden, crisp topping, switch oven to broil for the last 2-3 minutes. Watch closely to prevent burning. Remove once cheese topping is golden and slightly caramelized.
- Remove casserole from oven. Rest on a wire rack for 5-10 minutes before serving; this resting period helps the casserole set for clean portioning. Garnish with 2 tbsp (10g) fresh chopped parsley, if desired, before serving warm.
Notes
- Prepare the casserole mixture (up to Step 7) up to 24 hours in advance. Cover the baking dish tightly with plastic wrap or foil and refrigerate. Remove from the fridge 30 minutes prior to baking. Add 10-15 minutes to the baking time if baking from cold.
- Substitute or incorporate other low-carb vegetables: fresh spinach (wilt and squeeze out excess water), sliced asparagus, or sautéed mushrooms. Cook or lightly sauté any added vegetables before mixing to prevent excess moisture.
- Use pre-cooked rotisserie chicken for quicker preparation. Alternatively, boil or bake chicken breasts up to one day ahead. Cool chicken completely before shredding or dicing for the casserole.
- Vary cheese type: Use Gruyere, Monterey Jack, or a Colby-Jack blend. Use freshly shredded cheese for best melt and texture.
- Red pepper flakes are optional. For spicier casserole, increase to ½ tsp (2g) or more, as desired. Omit for a mild dish.
Pro Tips for a Perfect Low Carb Chicken Casserole
Ingredient Tips
- Cooked Chicken Texture:Shred or dice your cooked chicken into consistent 1/2-inch pieces. This size ensures the chicken evenly absorbs the creamy sauce and maintains its moisture, preventing dry, isolated bites.
- Turkey Bacon Crisping:Pan-fry 6-8 strips of turkey bacon over medium heat for 8-10 minutes, flipping every 2 minutes. Cook until deeply golden brown and audibly crisp, not just lightly browned, then crumble into 1/4-inch pieces for optimal crunch.
- Cheese Selection:Grate 8 ounces of cheddar or Monterey Jack cheese yourself from a block. Pre-shredded cheese contains starches that can make the sauce grainy; freshly grated cheese melts significantly smoother and yields a silkier texture.
- Cream Cheese Softening:Ensure 8 ounces of full-fat cream cheese is softened at room temperature for at least 30 minutes. It should be easily pliable when pressed; this prevents lumps and guarantees a velvety, uniform sauce consistency.
- Heavy Cream Richness:Use 1/2 cup of full-fat heavy cream (at least 36% milk fat) for the sauce. This higher fat content provides a noticeably richer flavor and thicker body compared to lower-fat creams, which can thin the casserole.
- Pre-cooking Vegetables:Steam 2 cups of 1-inch broccoli or cauliflower florets for exactly 3-4 minutes until fork-tender but still vibrant green and slightly firm. This prevents them from becoming mushy or watery during the casserole’s baking time.
- Layered Garlic Flavor:Incorporate 1 teaspoon of garlic powder into the sauce for a consistent, mellow garlic presence. For an added aromatic boost, briefly sauté 2 minced garlic cloves for 30 seconds in 1 tablespoon of olive oil before adding liquid.
Technique Tips
- Building the Cream Sauce:Over medium-low heat, combine 8 ounces softened cream cheese, 1/2 cup heavy cream, and 1/4 cup chicken broth. Whisk continuously for 3-4 minutes until the mixture is completely smooth, lump-free, and thick enough to lightly coat the back of a spoon.
- Folding Ingredients Gently:Once the sauce is ready, add the shredded chicken, 1.5 cups of grated cheese, crumbled turkey bacon, and pre-cooked vegetables. Fold gently for 30-45 seconds until all ingredients are just coated. Over-mixing can break down the chicken and make the sauce stringy.
- Optimal Baking Temperature:Preheat your oven to a precise 375°F (190°C) for a full 15 minutes before placing the casserole inside. This ensures the oven temperature is stable, promoting even cooking and a consistent golden-brown crust.
- Visual Cues for Doneness:Bake the casserole uncovered for 20-25 minutes. It’s ready for the final cheese layer when the edges are visibly bubbling vigorously, and the center feels hot to the touch (internal temp of 165°F/74°C).
- Achieving a Golden Crust:After the initial bake, sprinkle the remaining 1/4 cup shredded cheese evenly over the top. Return to the oven for an additional 8-10 minutes, until the cheese is melted, deeply golden brown, and bubbling with slightly crisped edges.
- Crucial Resting Period:Remove the casserole from the oven and allow it to rest undisturbed on a wire rack for 10-15 minutes before serving. This allows the creamy sauce to set properly, preventing it from being too runny and ensuring clean, well-defined portions.
Common Issues
- Runny Casserole Sauce:If your sauce is too thin after baking, return the casserole to a 375°F (190°C) oven for an additional 5-7 minutes, uncovered, to allow more moisture to evaporate. Next time, add 1 tablespoon of cream cheese or 1/4 cup more shredded cheese to the sauce mixture.
- Dry Chicken:Ensure chicken is shredded into 1/2-inch pieces and thoroughly coated in sauce. If using fresh raw chicken, cook it to an exact internal temperature of 165°F (74°C) only. If mixture seems dry before baking, stir in an extra 1/4 cup heavy cream.
- Bland Flavor Profile:Increase seasoning intensity. Add an extra 1/2 teaspoon of onion powder and 1/4 teaspoon of smoked paprika to the sauce. A tiny pinch (1/8 teaspoon) of cayenne pepper can also subtly lift the flavors without adding noticeable heat.
- Rubbery Turkey Bacon:Turkey bacon must be cooked until rigid and deeply golden brown, typically 8-10 minutes on medium heat. If it’s flexible, continue cooking for 1-2 more minutes, pressing it flat with a spatula, then drain promptly on paper towels.
- Soggy Vegetables:Pre-cook vegetables until barely tender. Steam broccoli/cauliflower for only 3-4 minutes until bright green and still firm. If using frozen spinach, thaw completely and squeeze out at least 1/4 cup of excess water before adding.
Low Carb Ingredient Substitutions & Variations
Essential Substitutions
- Cooked Chicken:
- (Canned chicken is very convenient but often softer and less robust in flavor. Rotisserie chicken adds rich, complex savory depth from its seasonings and saves significant prep time.)
- Turkey Bacon:
- (Pork bacon adds significantly richer, smokier flavor and higher fat. Crisped prosciutto offers a saltier, more delicate crisp with a distinct cured pork taste.)
- Full-fat Cream Cheese:
- (Mascarpone adds sweeter, more luxurious creaminess and slightly higher fat. Neufchâtel reduces fat by about one-third, maintaining a similar tang and texture.)
- Heavy Cream:
- (Provides similar thick consistency and creaminess, with a subtle, sweet coconut flavor. Ensure full-fat coconut cream is used for desired richness.)
- Broccoli Florets:
- (Cauliflower is milder, softer when cooked, and absorbs flavors well. Fresh spinach drastically reduces bulk when wilted, adding an earthy, slightly bitter green note.)
Dietary Variations
- Dairy-Free:
- Replace 1 cup full-fat cream cheese with 1 cup vegan cream cheese, replace 1/2 cup heavy cream with 1/2 cup full-fat coconut cream, and replace 1.5 cups shredded cheddar with 1.5 cups dairy-free shredded cheese.
- (Maintains creaminess and cheesy flavor without dairy. Note that vegan cheeses may melt differently, affecting final texture.)
- Vegetarian:
- Replace 2 cups cooked shredded chicken with 2 cups cooked green or brown lentils (rinsed and drained) OR 1.5 cups crumbled and sautéed extra-firm tofu. Omit turkey bacon or replace with 1/2 cup sautéed, finely diced mushrooms (cremini or button).
- (Changes the protein source, introducing varied plant-based textures and earthy flavors.)
- Lower Fat:
- Replace 1 cup full-fat cream cheese with 1 cup Neufchâtel cheese, replace 1/2 cup heavy cream with 1/2 cup half-and-half, and use 1 cup sharp cheddar cheese instead of 1.5 cups mild cheddar.
- (Significantly reduces fat and calories. Sauce will be slightly thinner, but sharp cheddar maintains prominent cheese flavor despite reduced quantity.)
Flavor Variations
- Spicy Southwest:
- Add 1/2 cup drained canned diced green chiles and 1/2 teaspoon chili powder along with 1/4 teaspoon cayenne pepper to the sauce mixture.
- (Introduces mild to medium heat and a distinct Tex-Mex flavor.)
- Garlic Herb Garden:
- Incorporate 2 cloves minced fresh garlic (in addition to any garlic powder) and 2 tablespoons fresh chopped parsley or chives into the sauce.
- (Brightens with vibrant, fresh aromatics and a pungent garlic kick, enhancing the savory profile.)
- Umami Bomb:
- Add 1 tablespoon Worcestershire sauce (ensure low carb) or 1 teaspoon umami seasoning blend, and 1/2 cup sliced sautéed mushrooms to the vegetable mix.
- (Deepens savory flavor significantly, adding complexity and rich, earthy undertones.)
