Step‑by‑Step Instructions for Cheesy Vegetable Casserole with Buttery Cracker Topping
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This temperature is perfect for baking your Cheesy Vegetable Casserole evenly, ensuring that the flavors meld beautifully while creating a delightful, golden crust on top.
Step 2: Sauté the Onions
In a large pot, melt 4 tablespoons of butter over medium heat. Add the diced onion and sauté for about 5 minutes or until the onions are translucent and aromatic. This step sets the foundation for a flavorful casserole, providing sweetness and depth to the dish.
Step 3: Create the Creamy Base
Stir in 1 can of cream of mushroom soup, along with 1 cup of milk, and 1 cup of sour cream. Season with 1 teaspoon of garlic salt, a pinch of salt, 1 teaspoon of mustard powder, and 1 teaspoon of Italian seasoning. Mix thoroughly until well combined and smooth, allowing the mixture to heat through for a couple of minutes.
Step 4: Melt the Cheese
Gently fold in 2 cups of shredded cheddar cheese into the creamy mixture, stirring continuously until the cheese melts completely. This will contribute creamy richness to your Cheesy Vegetable Casserole, ensuring every bite is decadent and flavorful.
Step 5: Mix in the Vegetables
Add 2 cups of frozen broccoli and any additional mixed vegetables you desire. Continue to cook for a few more minutes until everything is heated through. The vibrant colors and nutritious elements are essential for this Vegetable Casserole, enhancing both flavor and texture.
Step 6: Stir in the Eggs and Rice
Remove the pot from heat and carefully stir in 2 whisked eggs along with 2 cups of cooked rice. Mix until all ingredients are evenly incorporated, creating a cohesive mixture that binds your casserole together and promotes a hearty, satisfying dish.
Step 7: Assemble the Casserole
Pour the prepared mixture into a greased 9×13-inch casserole dish, spreading it evenly. This ensures that every scoop of your Cheesy Vegetable Casserole has consistent deliciousness and is easy to serve later on.
Step 8: Add the Topping
Sprinkle an additional cup of shredded cheese over the top of the casserole. Then, cover it with foil and bake for 20 minutes. The foil helps to steam the casserole gently, ensuring it heats evenly and all the flavors meld wonderfully.
Step 9: Bake for a Crispy Finish
Remove the foil and sprinkle crushed Ritz crackers generously on top. Continue baking uncovered for an additional 10 minutes or until the topping is golden brown and crispy. You’ll love how the buttery, crunchy texture contrasts with the creamy filling.
