![To make this delicious cheesy summer squash and zucchini casserole, gather these items: - 2 medium zucchini, sliced into thin rounds - 2 medium yellow squash, sliced into thin rounds - 1 cup shredded cheddar cheese - 1 cup shredded mozzarella cheese - 1/2 cup grated Parmesan cheese - 1 medium onion, finely chopped - 3 cloves garlic, minced - 1 cup heavy cream - 2 large eggs - 1 teaspoon dried thyme - 1 teaspoon dried oregano - Salt and pepper to taste - 1 cup breadcrumbs (preferably seasoned) - 2 tablespoons olive oil For the best flavor, use fresh squash. Choose firm, shiny zucchini and yellow squash. Look for cheese that melts well, like a good quality cheddar and mozzarella. Fresh herbs can elevate the dish, so consider using fresh thyme and oregano if possible. When buying breadcrumbs, pick ones that are seasoned for added depth. You can make this casserole fit many diets. For a lighter version, swap heavy cream for low-fat milk or a plant-based milk. Use egg substitutes like flaxseed meal or commercial egg replacers if needed. For a gluten-free option, use gluten-free breadcrumbs. If you want a dairy-free dish, try vegan cheese and cream alternatives. This recipe is flexible, so feel free to get creative! For the complete recipe, check out the [Full Recipe]. Start by gathering all your ingredients. You’ll need zucchini, yellow squash, and cheese. Slice the zucchini and squash into thin rounds. This helps them cook evenly. Chop the onion finely and mince the garlic. Sauté the onion in olive oil. Cook it until it looks clear, about five minutes. Add the garlic and cook for one more minute. This step brings out their flavors. In a large bowl, mix heavy cream, eggs, thyme, oregano, salt, and pepper. Whisk it until combined. Now, it’s time to layer the casserole. Take your greased baking dish and begin with half of the sliced zucchini and squash. Spread them evenly across the bottom. Next, add half of the sautéed onion and garlic. Pour half of the cream mixture over the veggies. Then sprinkle half of the cheddar and mozzarella cheese on top. Repeat this process with the rest of the squash and zucchini. Follow with the remaining onion and garlic, then the cream mixture, and finish with the rest of the cheese. Once your layers are complete, sprinkle breadcrumbs over the top. Add the grated Parmesan cheese for a nice finish. Bake your casserole in a preheated oven at 350°F for 40-45 minutes. You want the top to be golden brown and bubbly. After baking, let it cool for about ten minutes. This helps it set up. Serve it warm and enjoy! For extra flair, garnish with fresh parsley or serve with a salad. You can find the full recipe [here](Full Recipe). To avoid a watery casserole, salt your zucchini and squash. The salt pulls out moisture. After slicing, let them sit for 10-15 minutes. Then, pat them dry with paper towels. This step helps keep your dish thick and creamy. Using a mix of cheeses makes the casserole rich and tasty. I love using cheddar for sharpness, mozzarella for stretch, and Parmesan for a nutty flavor. The three together create a perfect balance. Feel free to try gouda or feta for a twist! For added flavor, you can mix in herbs and spices. Fresh basil or chives can brighten the dish. You can also add cooked bacon or sausage for a protein boost. For a spicy kick, sprinkle in some red pepper flakes. {{image_2}} You can keep the casserole vegetarian by sticking to the veggies. Add mushrooms, bell peppers, or spinach for extra flavor. These vegetables mix well with the summer squash and zucchini. You can also use different cheeses. Try goat cheese or feta for a unique taste. This gives a new twist without losing the cheesy goodness. To make the casserole heartier, add protein. Cooked chicken or sausage works great. I like to use grilled chicken for a light touch. If you choose sausage, go for a mild or spicy one, depending on your taste. Just slice it and layer it in with the veggies. This makes the dish filling and satisfying. For those who need gluten-free options, swap breadcrumbs for gluten-free breadcrumbs. You can also use crushed cornflakes or ground almonds. These alternatives keep the crunchy top you love. Always check labels to ensure they are truly gluten-free. This way, everyone can enjoy this tasty dish! Store any leftover cheesy summer squash and zucchini casserole in an airtight container.
