Ingredients

  • 1 lb (450 g) ground turkey
  • 1 tablespoon olive oil (15 ml)
  • 1 medium onion, finely chopped
  • 3 cloves garlic, minced
  • 5 cups fresh spinach (150 g), roughly chopped
  • 1 teaspoon salt (5 g)
  • ½ teaspoon black pepper (2 g)
  • 1 teaspoon paprika (5 g)
  • ½ teaspoon dried oregano (2 g)

For the Creamy Sauce:

  • 2 tablespoons butter (30 g)
  • 2 tablespoons all-purpose flour (16 g)
  • 2 cups milk (480 ml)
  • ½ cup cream (120 ml)
  • 1 cup shredded mozzarella cheese (100 g)
  • ½ cup grated cheddar cheese (50 g)
  • ¼ teaspoon nutmeg (optional)


Step-by-Step Instructions

1. Preheat and Prepare

Preheat your oven to 375°F (190°C). Lightly grease a medium-sized casserole dish and set aside.


2. Cook the Turkey

Heat olive oil in a large skillet over medium heat. Add chopped onion and sauté for 3–4 minutes until softened.

Add garlic and cook for about 1 minute until fragrant.

Add ground turkey and cook until browned, breaking it up as it cooks (about 6–8 minutes).

Season with salt, pepper, paprika, and oregano.


3. Add the Spinach

Add the fresh spinach gradually and stir until wilted. This should take 2–3 minutes.

Remove from heat once everything is well combined.


4. Make the Creamy Sauce

In a saucepan, melt butter over medium heat. Whisk in flour and cook for 1–2 minutes.

Slowly add milk while whisking continuously to prevent lumps.

Pour in the cream and cook until the mixture thickens (4–5 minutes).

Add mozzarella and cheddar cheese, stirring until melted and smooth. Add nutmeg if desired.


5. Assemble the Casserole

Transfer the turkey and spinach mixture into the prepared casserole dish.

Pour the creamy sauce evenly over the top and gently mix to combine.

Smooth the surface and add extra cheese on top if desired.


6. Bake

Bake for 20–25 minutes, or until the top is golden and bubbling.

Let the casserole rest for 5–10 minutes before serving.


Tips for Best Results

  • Use fresh spinach for better texture, but frozen can work if drained well
  • Avoid overcooking the sauce to keep it silky and smooth
  • Let it rest after baking so the casserole sets properly
  • Add texture if desired with mushrooms or zucchini
  • Use full-fat dairy for the creamiest result

Optional Add-Ins (No Pasta Needed)

Even without pasta, you can bulk up the casserole:

  • 1 cup mushrooms (150 g), sliced
  • 1 zucchini (150 g), diced
  • 1 cup cauliflower florets (150 g), lightly steamed
  • ½ cup cooked lentils (100 g) for added protein

Storage and Reheating

  • Refrigerator: Store up to 4 days in an airtight container
  • Freezer: Freeze for up to 2 months
  • Reheating: Warm in oven at 350°F (175°C) or microwave until hot

Frequently Asked Questions

1. Will the casserole still be filling without pasta?

Absolutely. While pasta often adds bulk, this casserole is still very satisfying thanks to the protein-rich ground turkey and fiber-packed spinach. The creamy sauce also adds richness that makes the dish feel complete. If you’re worried about it not being filling enough, you can easily add vegetables like cauliflower or zucchini to give it more substance without relying on pasta. Many people actually find this version more satisfying because it’s lighter but still hearty.


2. Can I make this recipe low-carb or keto-friendly?

Yes, this recipe is already quite close to low-carb. To make it fully keto-friendly, you can replace the flour in the sauce with a low-carb thickener like almond flour (use 2 tablespoons / 16 g) or simply reduce the sauce longer to thicken naturally. Also ensure your milk is replaced with a lower-carb option like heavy cream diluted with water. The rest of the ingredients—turkey, spinach, and cheese—fit perfectly into a keto lifestyle.


3. How do I prevent the casserole from becoming watery?

The key is managing moisture, especially from the spinach. If you’re using fresh spinach, cook it just until wilted and allow excess liquid to evaporate. If using frozen spinach, thaw it completely and squeeze out as much water as possible before adding it. Also, make sure your sauce is thick before combining it with the other ingredients. A properly thickened sauce helps bind everything together and prevents excess liquid from forming during baking.


4. Can I prepare this casserole in advance?

Yes, this is an excellent make-ahead meal. You can fully assemble the casserole, cover it tightly, and refrigerate it for up to 24 hours before baking. When ready to cook, simply bake it as directed, adding a few extra minutes if needed. This makes it ideal for busy schedules or when preparing meals ahead of time. You can also freeze it before baking and cook it later for a convenient, ready-to-go dinner option.


Final Thoughts

This no-pasta ground turkey and spinach casserole proves that comfort food doesn’t need to be heavy to be satisfying. By removing pasta, the dish becomes more focused on wholesome ingredients while still delivering the creamy, rich texture that makes casseroles so appealing.

What makes this recipe truly special is its versatility. It adapts easily to different dietary needs—whether you’re reducing carbs, increasing protein, or simply trying to incorporate more vegetables into your meals.

It’s the kind of meal that feels just as appropriate for a quiet night at home as it does for sharing with loved ones.
