Keto meals often need to be filling and simple to put together. Casseroles meet that need since they use one pan and basic ingredients. This list includes ten recipes that focus on flavor without extra steps. Each one works for weeknight dinners or making ahead. You can look through them and choose what fits your usual shopping list.
Helpful Tips Before You Start
These tips will help your keto casseroles turn out creamy and full of flavor.
Use Full-Fat Dairy
Full-fat cream cheese, heavy cream, and shredded cheese create the right texture and keep carbs low.
Cook Vegetables Ahead
Saute or roast vegetables first to remove excess water that can make casseroles soggy.
Season Each Layer
Sprinkle salt, pepper, garlic powder, or herbs between layers so the flavor reaches every bite.
Rest Before Serving
Let the casserole sit for 10 minutes after baking so it sets and slices cleanly.
Creamy Tuscan Chicken Casserole
This casserole combines tender chicken pieces with a rich cream sauce, spinach, and sun-dried tomatoes for a satisfying low-carb meal. It works well for busy weeknights or weekend meal prep since it holds up nicely in the fridge and reheats without losing texture. The result is a creamy, savory dish with bright tomato notes and a slight chew from the wilted greens.
Serves 4 people.
Ingredients
- 1.5 pounds boneless skinless chicken thighs, cut into bite-size pieces
- 2 tablespoons olive oil
- 4 cloves garlic, minced
- 1 cup heavy cream
- ½ cup grated Parmesan cheese
- ¾ cup sun-dried tomatoes packed in oil, drained and chopped
- 4 cups fresh spinach
- 1 teaspoon Italian seasoning
- ½ teaspoon salt
- ¼ teaspoon black pepper
- 1 cup shredded mozzarella cheese
Instructions
- Preheat the oven to 375°F and lightly grease a 9×9-inch baking dish.
- Heat the olive oil in a large skillet over medium heat. Add the chicken pieces and cook until lightly browned on all sides, about 6 minutes.
- Stir in the minced garlic and cook for 1 minute until fragrant.
- Pour in the heavy cream, then add the Parmesan cheese, sun-dried tomatoes, Italian seasoning, salt, and pepper. Stir until the cheese melts and the sauce thickens slightly.
- Add the spinach in batches, stirring until it wilts into the sauce.
- Transfer the mixture to the prepared baking dish and spread it evenly. Sprinkle the shredded mozzarella over the top.
- Bake for 20 minutes until the cheese is melted and the edges are bubbling. Let it rest for 5 minutes before serving.
Extra Tips
Use chicken thighs for the best moisture in the finished casserole. If the sauce seems too thick after adding the cream, splash in a tablespoon or two of the sun-dried tomato oil. Leftovers keep well in an airtight container in the fridge for up to three days and reheat gently on the stovetop or in the microwave with a splash of cream to loosen the sauce.Course: Main Course Cuisine: Italian Equipment: Large skillet, 9×9 baking dish, Oven
