HOW TO MAKE HEARTY BAKED VEGETABLE CASSEROLE WITH CREAMY CHEESE SAUCE
Let’s bring these ingredients together step by step to achieve that perfect balance of textures and flavors. From blanching veggies to baking until bubbly, follow along for a fuss-free yet impressive dinner.
1. Preheat your oven to 375°F (190°C) and grease a 9×13 inch baking dish to prevent sticking and encourage even browning.
2. In a large pot, bring water to a rolling boil. Lightly blanch the broccoli, cauliflower, and carrot slices for 3–4 minutes—just until they’re bright in color and slightly tender. Quickly drain and transfer to a bowl to halt cooking.
3. Heat olive oil in a large skillet over medium heat. Add the diced onion and sauté until translucent, about 5 minutes, stirring occasionally. Stir in minced garlic and cook for an additional minute until fragrant.
4. Add chopped bell peppers to the skillet and continue cooking for 3–4 minutes, stirring so they soften evenly. Season with salt, pepper, dried thyme, and dried basil, ensuring the peppers are laced with herbal goodness.
5. In a separate bowl, whisk together milk and flour until completely smooth. Incorporate cream cheese, Dijon mustard, paprika, optional cayenne pepper, and half of the cheddar and mozzarella. Keep whisking until the sauce is silky and free of lumps.
6. In a large mixing bowl, gently combine the blanched vegetables, cooked quinoa or brown rice, and the sautéed onion–pepper mixture. Pour the creamy cheese sauce over everything and stir until each piece is thoroughly coated.
7. Transfer the mixture into the prepared baking dish. Evenly top with the remaining cheddar and mozzarella, then sprinkle breadcrumbs if you’d like a crunchy finish.
8. Bake for 25–30 minutes, or until the casserole is bubbly around the edges and golden brown on top.
9. Remove from the oven and let it rest for a few minutes before serving. Enjoy your hearty vegetable casserole while it’s still warm and cheesy!
