Ground Turkey and Broccoli Casserole

350°F for 35 to 40 minutes makes a creamy ground turkey and broccoli casserole when you start with cooked rice and fully cooked turkey. Brown raw ground turkey separately before assembling the casserole, then use broccoli, mushrooms, a light creamy sauce, and cheddar for a filling weeknight meal. This guide includes the dependable cooked-rice version plus a separate uncooked-rice bake for times when you want to cook the rice in the casserole.

What Ground Turkey and Broccoli Casserole Needs

For the cooked-rice casserole, cook the ground turkey first, make the vegetable sauce, then combine both with cooked rice before baking. That order keeps raw poultry out of the finished casserole mixture and prevents the rice from absorbing sauce liquid while the dish bakes.

The cooked-rice method is especially useful for leftover turkey, meal-prepped rice, or ground turkey you cook fresh in a skillet. It also makes a lighter casserole than many cream-soup versions because the sauce uses milk and yogurt instead of heavy cream.

Cooked rice and uncooked rice are different casserole systems, not interchangeable starting points.

Use cooked white rice for the cooked-rice casserole. If you want to begin with dry rice and water, use the separate uncooked-rice method later in this article rather than simply adding dry rice to the creamy sauce.

How to Make Ground Turkey and Broccoli Casserole

Cooked turkey, rice, broccoli, mushrooms, and yogurt sauce bake in a 9 × 13-inch pan for 35 to 40 minutes.

Step One: Gather the Cooked-Rice Casserole Ingredients

The cooked-rice casserole makes 8 servings of about 1 cup each. The cooked-rice formula is based on the Texas A&M AgriLife Dinner Tonight turkey, broccoli, and rice casserole.

You will need:

12 ounces cooked ground turkey, measured after cooking, or chopped cooked skinless light-meat turkey
3 cups cooked white rice
2 1/2 cups chopped broccoli florets
1 cup mushroom pieces
1/4 cup chopped onion
2 tablespoons unsalted butter
2 tablespoons flour
1 1/2 cups 1% milk
1/2 cup nonfat yogurt
1/2 cup shredded low-fat cheddar cheese
1/2 teaspoon ground black pepper
1/2 teaspoon paprika

Use a 9 × 13-inch pan for the casserole. If you scale the recipe, keep the turkey, rice, vegetables, and sauce in proportion rather than adding extra rice alone.

Step Two: Heat the Oven and Prepare the Pan

Heat the oven to 350°F.
Lightly grease a 9 × 13-inch casserole dish.
Wash your hands, clean the work surface, and wash the broccoli and mushrooms before chopping them.

Cut the broccoli into small florets and slice or chop the mushrooms so they distribute through each serving instead of sitting in large pieces on top.

Step Three: Cook the Ground Turkey Before Assembly

Heat a skillet over medium heat.
Add enough ground turkey to yield 12 ounces after it is cooked.
Break it into small crumbles and cook for 8 to 10 minutes.
Check the thickest portion with a food thermometer; ground turkey must reach 165°F.
Transfer the cooked turkey to a bowl or plate.

The skillet step gives you evenly cooked crumbles and prevents the rice, sauce, and vegetables from overcooking while the poultry finishes.

If you are using leftover roasted or smoked turkey, skip the skillet step and measure 12 ounces of chopped cooked turkey.

Step Four: Make the Broccoli, Mushroom, and Yogurt Sauce

Melt the butter in the skillet over medium heat.
Add the broccoli, mushrooms, and onion.
Cook, stirring often, until the onion is tender.
Sprinkle the flour over the vegetables and butter, then stir until no dry flour remains.
Add the 1% milk, nonfat yogurt, black pepper, and paprika.
Stir until the sauce is blended and coats the vegetables.

Cooking the mushrooms with the broccoli matters because mushrooms release moisture. Letting that moisture cook into the sauce gives you a creamy casserole instead of a watery layer at the bottom of the pan.

Step Five: Assemble and Bake the Casserole

Combine the cooked turkey, cooked white rice, and vegetable sauce in a large bowl.
Spread the mixture evenly in the prepared 9 × 13-inch casserole dish.
Sprinkle the low-fat cheddar evenly over the top.
Bake at 350°F for 35 to 40 minutes.

The casserole is ready when the edges are bubbly and the cheese is lightly browned. Take it out of the oven and let it stand briefly so the creamy sauce settles before spooning it into servings.

Step Six: Portion and Serve

Spoon the casserole into 8 portions of about 1 cup each. It is a complete meal on its own, but a crisp green salad, cranberry sauce, or roasted carrots make useful sides when you want a larger dinner.

For a heartier hunting-camp-style plate, serve the casserole with hot sauce or a sharp pickle on the side rather than adding extra salt to the casserole itself.

Make a Ground Turkey Broccoli Bake With Uncooked Rice

Use this alternative only when you want the rice to cook in the oven.

Ingredients for the Uncooked-Rice Version

1 package ground turkey
2 1/2 cups diced broccoli
1 cup diced onion
2 cups spinach
1 1/2 cups uncooked rice
4 1/2 cups water
1 1/3 cups shredded cheese
Salt, pepper, or other seasonings, if desired

Use the entire package of ground turkey for this uncooked-rice version; because package weights vary, do not treat it as the same 12-ounce cooked-turkey formula used for the cooked-rice casserole.

How to Bake It

Heat the oven to 400°F.
Sauté the broccoli and onion in a skillet until they begin to soften.
Add the ground turkey, crumble it well, and cook it for 8 to 10 minutes. Confirm the turkey reaches 165°F with a food thermometer.
Transfer the turkey and vegetables to a baking dish. Stir in the spinach, uncooked rice, water, and seasonings.
Bake for 45 to 50 minutes, stirring once or twice about halfway through the bake so the rice cooks evenly.
Add and mix in the cheese, then return the dish to the oven for 8 minutes so the cheese melts.
Serve when the rice is tender and the casserole no longer has a pool of unabsorbed water.

This version is less creamy than the cooked-rice casserole, but it is useful when you have dry rice and want a one-dish dinner without cooking rice separately.

Low-Fat, Mushroom, and Broccoli Variations

The main recipe is already a lower-fat option because it uses 1% milk, nonfat yogurt, and low-fat cheddar.

Add More Mushrooms

For a stronger mushroom flavor, use a mix of white button mushrooms and cremini mushrooms while keeping the total amount close to 1 cup. Slice them thinly and cook them with the broccoli and onion so their moisture has time to cook into the sauce.

Use Frozen Broccoli

Frozen broccoli works well when fresh broccoli is not available. Add it to the skillet and cook until it is hot and excess moisture has evaporated before stirring in the flour, milk, and yogurt.

Use Leftover Turkey Instead of Ground Turkey

Chopped leftover roasted, smoked, or trash-can-cooked turkey can replace the cooked ground turkey. Use 12 ounces of cooked turkey and assemble the casserole with 3 cups cooked white rice. The oven bake warms the turkey while the sauce bubbles and the cheese browns.

Make It More Filling

Add spinach, diced carrots, or a side of roasted vegetables rather than adding extra rice. More rice can absorb the sauce and leave the casserole dry, while vegetables add bulk without changing the sauce balance as much.

Store, Freeze, and Reheat the Casserole Safely

Refrigerate leftover casserole in shallow containers within 2 hours of serving. Separate it into meal-size portions so it cools faster and is easy to reheat without repeatedly warming the whole pan.

Freeze cooled portions in freezer-safe containers or tightly wrapped pans. Label the container so you know what it is and when you froze it.

To reheat refrigerated or frozen cooked casserole, warm it until the center reaches 165°F. Covering the dish while reheating helps hold in moisture; uncover it near the end if you want the cheese topping to dry slightly and regain some texture.

How to Tell Ground Turkey and Broccoli Casserole Is Ready

Use these checks before serving:

The cheese is melted and lightly browned.
The edges of the casserole are actively bubbling.
The sauce looks creamy rather than thin or watery.
Broccoli is tender but still green.
In the uncooked-rice version, the rice is tender and the water is absorbed.

If the top browns before the middle is bubbling, loosely cover the dish with foil and continue baking until the center is hot. If the casserole seems loose right out of the oven, let it stand briefly; the sauce thickens as it settles.

Frequently Asked Questions

Can I use ground turkey and mushrooms in the same casserole?

Yes. Ground turkey and mushrooms can be used together in the cooked-rice casserole. Use 12 ounces of cooked ground turkey with 1 cup of mushrooms, 2 1/2 cups broccoli, and cooked rice for a balanced casserole. Sauté the mushrooms with the broccoli and onion before making the sauce so they do not release excess water in the oven.

Can I make this ground turkey broccoli casserole low fat?

Yes. The cooked-rice casserole uses a lighter sauce made with 1% milk, nonfat yogurt, and low-fat cheddar cheese. The lighter sauce uses 1 1/2 cups 1% milk, 1/2 cup nonfat yogurt, and 1/2 cup shredded low-fat cheddar cheese. It remains creamy because flour thickens the milk and yogurt mixture around the vegetables and rice.

Can I use leftover turkey instead of ground turkey?

Yes. Chopped cooked turkey can replace the cooked ground turkey in this casserole. Use 12 ounces of chopped cooked turkey in place of the cooked ground turkey. Bake the assembled cooked-rice casserole at 350°F for 35 to 40 minutes, until the edges bubble and the top is lightly browned.

Can I use Knorr cheesy broccoli mix in this casserole?

Knorr cheesy broccoli mix is not a direct substitute for the milk-and-yogurt sauce in this recipe. Cheesy broccoli packet mixes can have different liquid needs, salt levels, and rice components, so use a recipe designed specifically for that packet rather than adding it to the cooked-rice casserole formula without adjusting the liquids.

Can I make this casserole with uncooked rice?

Yes, but use the uncooked-rice method: 1 1/2 cups uncooked rice and 4 1/2 cups water bake at 400°F for 45 to 50 minutes, with one or two stirs halfway through. Add the cheese afterward and bake for 8 more minutes to melt it.

How do I keep ground turkey from becoming dry?

Cook the turkey only until it reaches 165°F, then fold it into the sauce and rice rather than continuing to fry it. The creamy vegetable sauce protects the turkey during the oven bake and keeps the finished casserole from tasting chalky or dry.
