How to Make Zucchini Pizza Casserole
Prep the Zucchini: Start by shredding or slicing the zucchini. Sprinkle it with salt and let it sit for about 10 minutes, allowing the excess moisture to draw out. Squeeze it out gently afterward for a perfect texture.
Cook the Meat: In a skillet over medium heat, brown the ground turkey or beef until fully cooked. Make sure to drain any excess fat and set the meat aside to keep it light and tasty.
Make the Sauce: In the same skillet, heat olive oil and saut minced garlic and chopped onion until fragrant and soft. Add the pizza sauce and Italian seasoning, letting it simmer for 5 minutes to meld those delicious flavors together.
Assemble the Casserole: Grease a 9 13 ³ baking dish and begin layering. Start with the zucchini, then spoon the meat sauce on top, finishing off with generous layers of mozzarella and Parmesan cheeses.
Bake: Place the dish in a preheated oven at 375 °F (190 °C) and bake for 30-35 minutes, or until the cheese is bubbling and golden brown. Once it s out, allow it to rest for 5-10 minutes before serving to let those flavors settle.
Optional: Garnish with fresh basil or chili flakes for an extra kick!
