Ingredients Method

Ingredients

  

• 1 pound ground chicken (93–96% lean works best)
• 1 tablespoon olive oil
• 1 small yellow onion, finely chopped
• 3 cloves garlic, minced
• 1 teaspoon kosher salt, divided (adjust to taste)
• 1/2 teaspoon black pepper
• 1 teaspoon dried Italian seasoning (or 1/2 tsp dried oregano + 1/2 tsp dried basil)
• 1/4 teaspoon crushed red pepper flakes (optional, for mild heat)
• 1 (24-ounce) jar marinara sauce (choose a no-sugar-added brand you like)
• 1/2 cup low-sodium chicken broth (or water)
• 1/2 cup plain Greek yogurt (2% or 5%) or light cream
• 1/3 cup grated Parmesan cheese, plus more for serving
• 1 (20-ounce) package refrigerated cheese tortellini (or 18–20 ounces frozen, thawed)
• 1 cup shredded part-skim mozzarella
• 2 cups baby spinach, roughly chopped (optional but recommended)
• Fresh basil or parsley, chopped, for garnish (optional)
• Cooking spray

Method

 

1. Preheat and prep: Heat your oven to 375°F (190°C). Lightly coat a 9x13-inch baking dish with cooking spray.
2. Sauté aromatics: In a large skillet over medium heat, warm the olive oil. Add the onion and a pinch of salt. Cook 3–4 minutes until softened. Stir in the garlic and cook 30 seconds until fragrant.
3. Brown the chicken: Add the ground chicken, breaking it up with a spatula. Season with 1/2 teaspoon salt, pepper, Italian seasoning, and red pepper flakes if using. Cook 5–7 minutes until no pink remains and lightly browned.
4. Build the sauce: Stir in the marinara and chicken broth. Bring to a gentle simmer for 2–3 minutes to meld flavors. Reduce heat to low.
5. Add creaminess: Remove the skillet from heat. Whisk in the Greek yogurt (or light cream) and Parmesan until smooth. Taste and adjust seasoning with a pinch more salt if needed.
6. Combine with tortellini: In a large bowl, add the tortellini and chopped spinach. Pour the sauce over and toss to coat evenly.
7. Assemble the casserole: Transfer the mixture to the prepared baking dish. Sprinkle mozzarella evenly on top, then an extra dusting of Parmesan if you like.
8. Bake: Cover loosely with foil and bake for 15 minutes. Remove foil and bake 8–10 more minutes, until the cheese is melted and bubbling and the edges are lightly golden.
9. Rest and garnish: Let the casserole rest 5 minutes so it sets slightly. Top with fresh basil or parsley. Serve hot with extra Parmesan at the table.

• Freezer: Freeze in portioned, freezer-safe containers for up to 2 months. Thaw overnight in the fridge.
• Reheat: Microwave individual servings for 1–2 minutes, stirring halfway. For best texture, reheat covered in a 350°F (175°C) oven for 15–20 minutes until warmed through.

  Add 5–10 minutes to the bake time if cold from the fridge.

Health Benefits

• Lean protein from chicken: Supports muscle maintenance, keeps you fuller, and pairs well with moderate carbs from the pasta.
• Calcium and protein from dairy: Parmesan, mozzarella, and Greek yogurt contribute protein and bone-friendly nutrients.
• Greens for micronutrients: Spinach adds iron, folate, vitamin K, and fiber with barely any effort.
• Smart swaps: Greek yogurt lightens the sauce compared to heavy cream while adding extra protein and a creamy texture.

What Not to Do

• Don’t overcook the tortellini before baking: If using refrigerated tortellini, no pre-boil is needed. Overcooking leads to mushy pasta.
• Don’t skip seasoning the chicken: Ground chicken is mild; seasoning in the pan builds flavor from the start.
• Don’t add yogurt over high heat: It can curdle. Take the skillet off the heat before whisking it in.
• Don’t overload with liquid: Stick to the broth amounts.

  Too much liquid prevents a cohesive, creamy bake.

• Don’t burn the top: If the cheese browns too fast, tent with foil for the last few minutes.

Variations You Can Try

• Extra-lean boost: Stir in a can of rinsed white beans or 1 cup cottage cheese into the sauce for more protein.
• Veggie-forward: Add sautéed mushrooms, zucchini, or bell peppers with the onions for more volume and nutrients.
• Spicy version: Use spicy marinara, bump the red pepper flakes, and add a pinch of smoked paprika.
• Pesto twist: Swap 1/3 cup of the marinara for basil pesto for a herb-forward, richer flavor.
• Different tortellini: Try spinach and cheese tortellini or chicken-filled tortellini for an extra protein push.
• Lactose-lighter: Use lactose-free yogurt and mozzarella; choose a marinara without added cheese.
• Gluten-conscious: Use gluten-free tortellini if available, and confirm the marinara is gluten-free.

FAQ

Can I use ground turkey instead of ground chicken?

Yes. Ground turkey works almost identically in this recipe. Choose 93% lean so it stays moist and flavorful.

Do I have to cook the tortellini first?

If using refrigerated tortellini, no pre-boil is necessary.

For frozen tortellini, thaw first. If using dried tortellini, parboil it for 2–3 minutes less than package directions before baking.

What if I don’t have Greek yogurt?

Use light cream, half-and-half, or even a mix of ricotta and a splash of milk. The yogurt adds protein and tang, but the recipe is flexible.

How can I make it lower in fat?

Use part-skim mozzarella, stick with Greek yogurt instead of cream, and go lighter on the cheese topping.

You can also increase spinach and reduce tortellini slightly.

Can I make this casserole dairy-free?

Yes. Use dairy-free tortellini and swap the yogurt and cheeses for plant-based alternatives. Choose a marinara without dairy.

The texture will still be creamy if you use a good dairy-free mozzarella.

Why did my sauce separate?

Yogurt can curdle if added over high heat. Remove the pan from heat before whisking it in, and ensure the sauce isn’t boiling. It will smooth out once baked.

How many servings does this make?

It comfortably serves 6 as a main dish.

If you’re feeding big appetites, plan on 5 servings; for lighter portions or with sides, you could stretch to 7–8.

What sides go well with this casserole?

A simple green salad with balsamic vinaigrette, roasted broccoli, or garlic green beans all pair nicely. Warm crusty bread works if you want a little extra comfort.

Can I cook it entirely on the stovetop?

Yes. Simmer the sauce with chicken and toss with tortellini until just tender.

Top with cheese, cover, and let it melt on low. You’ll miss the browned top, but it’s fast and tasty.

How do I prevent a watery casserole?

Measure liquids carefully, don’t add wet spinach straight from washing (pat dry), and avoid overcooking the tortellini. Let it rest 5 minutes after baking so the sauce sets.
