Ingredients

2 tablespoons butter (or olive oil) to start the pan. 1 medium onion to add sweet depth. 2 cloves garlic for aroma. 1 cup sliced mushrooms for an earthy texture. 1 cup broccoli florets for crunch and color. 1 cup cauliflower florets for a tender bite. 1 cup sliced carrots for natural sweetness. 1 cup frozen peas for bright color. 1 can cream of mushroom soup to bind the dish. ½ cup milk to thin the soup. ½ cup sour cream for extra creaminess. 1 cup shredded cheddar for melty flavor. Salt and black pepper to taste. 1 teaspoon dried thyme for light herb notes. 1 cup bread crumbs and ¼ cup Parmesan to make a crispy, salty top.

Tips to make this recipe

Use vegetables that are similar in size so they cook evenly. Don’t overcook them on the stove; they finish in the oven. If you want a thicker sauce, use less milk. For a dairy-free meal, swap butter, milk, sour cream, and cheeses with plant versions. Taste and salt at the end to avoid over-salting. If the top browns too fast, cover the dish with foil.

Variation

You can swap many parts of this version. Use bell peppers instead of carrots for a softer sweet note. Swap cauliflower for zucchini in summer. Use a different cheese like Monterey Jack or a vegan cheese. For a lighter top, use crushed crackers instead of bread crumbs. If you want a heartier meal, add cooked chicken or canned beans. Some swaps change the bake time slightly, so watch the center for doneness.
