Detailed Directions and Instructions
Step 1: Preheat the Oven
Preheat your oven to 400°F (204°C) so it is ready to bake the casserole.
Step 2: Prepare the Zucchini
Wash and slice the zucchini into thin, round pieces, approximately 1/4 inch thick. Gently pat them dry with a paper towel to remove any excess moisture, as this will prevent the casserole from becoming watery.
Step 3: Cook the Ground Beef
Heat a large non-stick pan over medium heat. Add ground beef and cook until browned, breaking it apart with a spatula. Once fully cooked, drain any excess grease and set the beef aside.
Step 4: Sauté the Onion and Garlic
In the same pan, heat about 1 tablespoon of olive oil over medium heat. Sauté the diced onion until soft and translucent, approximately 3-4 minutes. Add the minced garlic and cook for an additional 30 seconds, stirring occasionally to prevent burning.
Step 5: Combine Ingredients
In a large mixing bowl, combine the cooked ground beef with the onion, garlic, marinara sauce, ricotta cheese, half of the shredded mozzarella, and all of the parmesan. Mix together thoroughly until evenly incorporated.
Step 6: Assemble the Casserole
Lightly grease a 9×13-inch baking dish with cooking spray or olive oil. Begin layering the casserole starting with a layer of zucchini slices to cover the base of the dish completely. Spread half of the meat mixture over the zucchini. Add another layer of zucchini slices, and then spread the remaining half of the meat mixture on top. Finish with a final layer of zucchini slices.
Step 7: Add Cheese Topping
Top the assembled casserole with the remaining shredded mozzarella cheese, spreading it evenly over the top layer of zucchini.
Step 8: Bake
Cover the dish with foil and bake in the preheated oven for 25 minutes. After this, remove the foil and bake uncovered for an additional 15 minutes to allow the cheese to melt and turn golden.
Step 9: Let it Rest
Remove the casserole from the oven and allow it to sit for 5-10 minutes before slicing and serving. This helps it set and makes serving easier.
Notes
How to Prevent a Watery Casserole
Make sure to pat the zucchini slices dry with a paper towel before assembling the casserole. If your zucchini contains a lot of moisture, sprinkle a small amount of salt on the slices and let them sit for 10 minutes, then blot dry.
Substitution Options
If you prefer, you can use ground turkey or chicken instead of ground beef. Additionally, feel free to substitute ricotta cheese with cottage cheese or cream cheese for a different flavor.
