Step‑by‑Step Instructions for Squash Zucchini Ritz Casserole
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While it heats, generously grease a 9×13-inch casserole dish with cooking spray or butter to prevent sticking. This step sets the foundation for your delicious Squash Zucchini Ritz Casserole, ensuring it bakes evenly and beautifully.
Step 2: Slice the Vegetables
Next, take your summer squash and zucchini, slicing them into uniform rounds about a quarter-inch thick. This helps them cook evenly and blend perfectly in the casserole. Aim for about three cups each of both vegetables, which will create a vibrant, colorful filling that’s both nutritious and delicious.
Step 3: Sauté the Onion and Garlic
In a large skillet over medium heat, melt about 3 tablespoons of butter. Add the finely chopped onion and sauté for 3-4 minutes until it turns translucent and fragrant. Stir in the minced garlic, cooking for an additional 30 seconds. This aromatic base enhances the flavors of your Squash Zucchini Ritz Casserole and infuses it with warmth.
Step 4: Combine Vegetables
Once sautéed, add the sliced summer squash and zucchini to the skillet, stirring them well with the onion and garlic. Cook for about 5 minutes, allowing the vegetables to soften slightly. This step melds the flavors together, making each bite of your casserole more satisfying.
Step 5: Whisk the Egg Mixture
In a separate mixing bowl, whisk together 2 beaten eggs, 1 cup of milk, and both cheeses—1 cup of shredded sharp cheddar and 0.5 cup of grated Parmesan. Add in dried thyme, salt, and black pepper to taste. This creamy mixture is essential to bind the vegetables in your Squash Zucchini Ritz Casserole, adding richness and flavor.
Step 6: Combine All Ingredients
Pour the egg and cheese mixture over the sautéed vegetables in the skillet, folding everything together gently but thoroughly. Once combined, transfer this colorful blend into the greased casserole dish. The layering of flavors here is what makes your casserole a true delight when it’s finally baked.
Step 7: Prepare the Topping
In a small bowl, mix 1.5 cups of crushed Ritz crackers with the remaining melted butter until well combined. This topping gives an irresistible crunch and buttery flavor to your casserole. Evenly sprinkle this buttery crushed cracker mixture over the top of the assembled vegetable blend in your casserole dish.
Step 8: Bake to Perfection
Place your prepared Squash Zucchini Ritz Casserole into the preheated oven and bake for 40-45 minutes. Look for bubbling edges and a golden, crispy topping as visual cues that your dish is ready. The aroma wafting through your kitchen is an added bonus as your casserole transforms into a comforting masterpiece.
Step 9: Let it Rest
Once baked, remove the casserole from the oven and allow it to cool for about 10 minutes. This resting period helps the casserole set and allows for cleaner slices when serving. The delightful combination of flavors and textures will be worth the wait as you prepare to indulge.
