Step‑by‑Step Instructions for Creamy Vegetable Casserole with Buttery Cracker Topping Step 1: Preheat and Prepare Begin by preheating your oven to 350°F (175°C). As the oven warms up, grab a large pot and set it over medium heat. This is where the magic of your Vegetable Casserole begins, so make sure to have all your ingredients ready to go for a smooth cooking process. Step 2: Sauté the Onions Melt a tablespoon of butter in the preheated pot. Once melted, add diced onions and sauté for about 5 minutes, stirring frequently until they become softened and translucent. The fragrant aroma will fill your kitchen, signaling that it’s time to move on to the next step of creating this creamy, comforting casserole. Step 3: Mix the Creamy Base Next, stir in the cream of mushroom soup along with milk and sour cream into the pot. Add garlic salt, salt, mustard powder, Italian seasoning, and pepper, mixing everything well together until it’s beautifully combined and smooth. Pay attention to the texture; it should be creamy and a bit thick as you prepare the delicious filling for the casserole. Step 4: Add Cheese To enhance the richness, incorporate 1 cup of shredded cheddar cheese into the creamy mixture. Stir continuously until the cheese fully melts and blends into the sauce, creating a luscious consistency. This cheesy goodness forms the backbone of the Vegetable Casserole, ensuring every bite is packed with flavor. Step 5: Incorporate Veggies Gently fold in the frozen broccoli and mixed vegetables into the creamy mixture, allowing them to heat slightly through. Stir for about 2-3 minutes until the vegetables are evenly coated and heated but not mushy. This step brings a delightful burst of color and nutrition to your casserole, making it as visually appealing as it is delicious. Step 6: Combine with Rice and Eggs Remove the pot from heat and let it cool slightly. Then, stir in the whisked eggs and cooked rice until fully combined with the vegetable mixture. This binding is crucial for the perfect texture in your Creamy Vegetable Casserole, so make sure everything feels cohesive and well-mixed before transferring to the baking dish. Step 7: Transfer to Casserole Dish Grease a casserole dish generously with butter or cooking spray. Carefully pour the vegetable mixture into the dish, spreading it evenly. Then, sprinkle the remaining shredded cheese over the top, which will melt into a bubbly, golden layer when baked, adding to the creamy indulgence of your casserole. Step 8: Bake Covered Cover the casserole dish with foil and place it in the preheated oven. Bake for 20 minutes, allowing all the flavors to meld together. This covered baking stage helps steam the casserole, ensuring it remains moist while the delicious aroma permeates your kitchen. Step 9: Prepare the Topping While the casserole bakes, combine the crushed Ritz crackers with melted butter in a small bowl. Mix until the crackers are evenly coated, creating a buttery topping that will add a lovely crunch to your Vegetable Casserole once it comes out of the oven. Step 10: Finish Baking After the initial 20 minutes, carefully remove the foil from the casserole. Evenly distribute the buttery cracker mixture on top and return the dish to the oven, baking uncovered for an additional 10 minutes. Watch for a golden brown finish, where the topping transforms into a crispy delight that perfectly complements the creamy filling. Step 11: Serve and Enjoy Once baked, remove the casserole from the oven and let it cool for a few minutes before serving. This Creamy Vegetable Casserole with Buttery Cracker Topping is best enjoyed warm, showcasing its creamy texture and crunchy topping, making it an irresistible side dish for any meal.

Make Ahead Options This Creamy Vegetable Casserole is a fantastic meal prep solution for busy cooks! You can assemble the entire casserole up to 24 hours in advance; simply cover it tightly with foil and refrigerate until you’re ready to bake.

When you’re ready to serve, you can bake it straight from the fridge, adding an extra 10-15 minutes to the cooking time to ensure it’s heated through. Prepping in advance not only saves time but also allows the flavors to meld, making your casserole just as delicious as when freshly made! Expert Tips for Creamy Vegetable Casserole Don’t Overcook Veggies: Vegetables should be tender but not mushy; this way, they retain their color and nutrition in the side dish. Taste Test Seasoning: Always check the seasoning before baking; adjusting the flavors ensures a perfect balance in your creamy casserole. Melted Butter is Key: Ensure that the butter for the topping is fully melted with the crushed crackers to achieve an even golden-brown crust.
