Step-by-Step Guide to Perfect Cheesy Beef & Spinach Tortellini Casserole

Preheat the Oven: Set your oven to 375°F (190°C) to ensure it’s hot and ready for baking.
Sauté Aromatics: In a large skillet, heat olive oil over medium heat. Add diced onion and minced garlic, sautéing until translucent, about 3-4 minutes.

Transfer to Baking Dish: Pour the mixture into a greased 9×13 inch baking dish, spreading it evenly to ensure even cooking.

Chef’s Notes & Pro Tips for Flawless Results

Make-Ahead Instructions: This casserole can be prepared ahead of time and stored in the refrigerator for up to 2 days before baking. Just cover it tightly with foil.

Storage: Leftovers can be stored in an airtight container in the fridge for up to 3 days. Reheat in the oven or microwave until warmed through.
Equipment Recommendations: Use a non-stick baking dish for easier cleanup and to prevent sticking.
Customization Options: Feel free to swap out the ground beef for ground turkey or chicken for a lighter version, or add other vegetables like bell peppers or mushrooms for extra flavor.

Avoid These Common Cooking Mistakes

Using Frozen Tortellini: This can lead to a mushy texture. Always use fresh or properly cooked frozen tortellini.
Overcooking the Beef: This can make it tough. Cook just until browned and drain excess fat.
Not Letting the Casserole Rest: Serving immediately can result in a runny texture. Always let it cool for a few minutes.

Using Too Much Sauce: This can make the dish soupy. Stick to the recommended amount for the best consistency.
Forgetting to Season: Not seasoning the layers can lead to bland flavors. Always taste and adjust seasoning as needed.
Not Covering the Dish: Skipping foil during the first half of baking can lead to burnt cheese. Cover to prevent over-browning.

Omitting Ricotta: Skipping this key ingredient can make the casserole less creamy. Don’t omit it for the best results.
