Ingredients

(Note: All ingredient amounts are listed in the recipe card below.)

• 1 cup chopped mushrooms sliced

• 2 cups frozen broccoli florets

• 1 tablespoon olive oil

• 1 teaspoon minced garlic

• 3 cups shredded cooked turkey 1 pound

• ½ teaspoon sea salt

• ½ teaspoon ground black pepper

• 2 ½ cups shredded cheese use your favorite cheese

• 1 ½ cups heavy cream

• 1 teaspoon minced parsley

Directions

Step 1: Preheat the Oven

I start by preheating my oven to 395°F (202°C). While the oven heats, I lightly grease a 9×13-inch baking dish to prevent the casserole from sticking.

I like using a large baking dish because it allows the ingredients to spread evenly, helping the cheese melt and brown beautifully.

Step 2: Prepare the Mushrooms

I wash or wipe the mushrooms clean and slice them into evenly sized pieces.

I prefer keeping the mushroom slices relatively thin so they cook quickly and blend nicely with the turkey and broccoli.

Step 3: Sauté the Vegetables

I heat the olive oil in a large skillet over medium heat.

Once the oil is warm, I add the sliced mushrooms, frozen broccoli florets, and minced garlic.

I cook everything for approximately 5 minutes, stirring occasionally, until the mushrooms begin to soften and the broccoli starts to heat through.

I love how the garlic adds a wonderful savory aroma while the mushrooms develop a richer flavor.

Step 4: Add the Turkey and Seasonings

Next, I stir the shredded cooked turkey into the skillet.

I season the mixture with sea salt, ground black pepper, and minced parsley.

I gently stir everything together so the turkey and vegetables are evenly coated with the seasonings.

Since the turkey is already cooked, I only need to warm it through rather than cook it again.

Step 5: Make the Creamy Cheese Sauce

I add 1 cup of shredded cheese and the heavy cream directly to the skillet.

I stir gently until the cheese begins melting into the cream, creating a smooth, rich sauce.

I bring the mixture to a gentle simmer, allowing the ingredients to combine and the sauce to thicken slightly.

I avoid boiling the cream rapidly because I want the sauce to remain smooth and creamy.

Step 6: Assemble the Casserole

I carefully transfer the turkey, broccoli, mushroom, and cheese mixture into my prepared baking dish.

Using a spatula, I spread everything into an even layer.

I sprinkle the remaining 1 ½ cups of shredded cheese over the top, making sure the casserole is evenly covered.

I love adding a generous cheese topping because it creates a delicious golden crust during baking.

Step 7: Bake Until Golden

I place the casserole in the preheated oven and bake for approximately 20 minutes.

I look for melted, bubbly cheese with a lightly golden surface.

If I want a little more browning, I can briefly place the casserole under the broiler while watching it carefully to prevent burning.

Step 8: Garnish and Serve

Once the casserole is ready, I remove it from the oven and let it rest for a few minutes.

I finish with a little extra parsley for color and freshness.

I enjoy serving this casserole warm, while the cheese is still melted and the sauce is rich and creamy.

Servings and Timing

I find this recipe especially convenient when I need a satisfying dinner without spending too much time cooking. With only 5 minutes of preparation and 30 minutes of cooking, I can have a warm, homemade meal ready in just over half an hour.

Variations

Chicken Broccoli Casserole

When I don’t have leftover turkey, I replace it with an equal amount of shredded cooked chicken. I find that chicken works beautifully with the creamy cheese sauce and broccoli, making this variation just as comforting.

Cheddar Turkey Broccoli Casserole

I sometimes use sharp cheddar cheese for a stronger, more pronounced cheese flavor. I love how cheddar melts into the heavy cream and creates a rich, savory sauce.

Turkey Broccoli Rice Casserole

For a heartier meal, I mix cooked rice into the turkey and broccoli mixture before baking. I find that rice absorbs some of the creamy sauce and makes the casserole even more filling. I add a little extra cream if the mixture looks too thick.

Turkey Broccoli Mushroom Casserole With Extra Vegetables

When I want to include more vegetables, I add diced bell peppers, spinach, or zucchini. I usually sauté the extra vegetables before combining them with the turkey so they release excess moisture and cook evenly.

Spicy Turkey Broccoli Casserole

I occasionally add crushed red pepper flakes, cayenne pepper, or a little hot sauce to the creamy mixture. I enjoy the subtle heat because it balances the richness of the cheese and heavy cream.

Low-Carb Turkey Broccoli Casserole

I love that the original recipe is already relatively low in carbohydrates. When I want to keep it that way, I serve it without rice, pasta, or bread and pair it with a fresh green salad.

Crispy Topped Turkey Casserole

For extra texture, I sometimes sprinkle seasoned breadcrumbs or crushed buttery crackers over the cheese before baking. I like how the crispy topping contrasts with the creamy filling.

Storage/Reheating

Refrigerating

I store leftover Turkey Broccoli Casserole in an airtight container in the refrigerator for up to 3–4 days.

I always allow the casserole to cool slightly before refrigerating it, and I make sure to refrigerate leftovers within 2 hours of cooking.

I prefer dividing the leftovers into individual portions because this makes reheating easier.

Freezing

I can freeze this casserole for up to 2–3 months, although I find that cream-based sauces sometimes change texture after thawing.

For the best results, I let the casserole cool, transfer it into a freezer-safe container, and seal it tightly.

When I’m ready to enjoy it again, I thaw it overnight in the refrigerator before reheating.

Reheating in the Oven

I preheat my oven to 350°F (175°C) and transfer the refrigerated casserole into an oven-safe dish.

I cover it loosely with aluminum foil to prevent the cheese from browning too much.

I reheat it for approximately 15–20 minutes, or until the center reaches 165°F (74°C).

If the casserole looks a little dry, I add a small splash of cream before reheating to restore its creamy texture.

Reheating in the Microwave

For individual portions, I place the casserole in a microwave-safe dish and cover it loosely.

I heat it in short intervals, stirring or checking between intervals until thoroughly heated.

I find that reheating gently helps keep the turkey tender and prevents the creamy sauce from separating.

Making Ahead

When I want to save time, I prepare the casserole mixture in advance and transfer it to the baking dish.

I cover it tightly and refrigerate it until I’m ready to bake, preferably within 24 hours.

Before serving, I bake it until the cheese is melted and the casserole is heated all the way through. I allow additional baking time if the mixture is coming directly from the refrigerator.

FAQs

1. Can I Use Leftover Thanksgiving Turkey for This Casserole?

Yes, I actually think leftover Thanksgiving turkey is perfect for this recipe. I shred the cooked turkey into bite-sized pieces and mix it with the broccoli, mushrooms, and creamy cheese sauce. I love how this recipe transforms holiday leftovers into a completely different meal without much extra work.

2. Can I Use Fresh Broccoli Instead of Frozen Broccoli?

Absolutely. I can substitute fresh broccoli florets for frozen broccoli. When using fresh broccoli, I cut it into small, evenly sized pieces and sauté it until it begins to soften. If the florets are especially large or firm, I blanch them briefly before adding them to the skillet.

3. What Is the Best Cheese for Turkey Broccoli Casserole?

I love using cheddar cheese because it provides a rich flavor and melts beautifully. However, I can also use Monterey Jack, mozzarella, Colby Jack, or a combination of cheeses. I prefer choosing cheeses that melt smoothly and complement the mild flavor of turkey.

4. Can I Make Turkey Broccoli Casserole Without Heavy Cream?

Yes, I can replace the heavy cream with half-and-half or a lighter creamy sauce. However, I find that heavy cream produces the richest texture. When using a lighter substitute, I may need to add a small amount of thickener to keep the sauce from becoming watery.

5. Why Is My Turkey Broccoli Casserole Watery?

I usually find that excess moisture comes from frozen broccoli or mushrooms releasing water during cooking. To prevent this, I sauté the vegetables long enough for some of the moisture to evaporate before adding the cream. I also allow the cheese sauce to simmer gently so it thickens slightly before baking.

6. Can I Prepare This Casserole the Night Before?

Yes, I often assemble the casserole the night before when I know I’ll have a busy day. I prepare the turkey, vegetable, and cream mixture, place it in the baking dish, and refrigerate it covered. When I’m ready to serve, I bake it until the center is thoroughly heated and the cheese topping is golden.

7. Can I Add Rice or Pasta to Turkey Broccoli Casserole?

Yes, I can add cooked rice or pasta to make the casserole more substantial. I prefer using fully cooked rice or pasta because the original recipe doesn’t contain enough extra liquid to cook them from dry. I sometimes add a little more cream or cheese sauce to keep the finished casserole moist.

8. How Do I Keep the Turkey From Drying Out?

I use cooked turkey that is still tender and avoid overheating it during the skillet stage. Since the turkey is already cooked, I only need to warm it and combine it with the sauce. I also make sure the shredded turkey is well coated with the creamy mixture before baking.

9. Can I Freeze Turkey Broccoli Casserole After Baking?

Yes, I can freeze the baked casserole once it has cooled. I transfer it into an airtight freezer-safe container and store it for up to 2–3 months for the best quality. I thaw it in the refrigerator before reheating. Although the cream sauce may separate slightly after freezing, I find that gentle reheating helps improve the texture.

10. What Can I Serve With Turkey Broccoli Casserole?

I love serving this casserole with a simple green salad, roasted vegetables, garlic bread, or fluffy rice. Since the casserole is already rich and creamy, I often choose a lighter side dish to balance the meal. For a more filling dinner, I pair it with mashed potatoes or warm dinner rolls.

Conclusion

Turkey Broccoli Casserole is one of my favorite easy comfort food recipes, especially when I have leftover turkey in the refrigerator. I love how the tender turkey, broccoli, mushrooms, garlic, and creamy cheese sauce come together to create a warm, satisfying dinner with minimal effort.
