Ingredients

Here’s everything you’ll need for my Best Veggie Casserole Recipe (serves 6):

Equipment

• Large casserole dish (9×13-inch or similar)
• Large mixing bowl
• Medium skillet
• Cutting board and knife
• Measuring cups and spoons
• Wooden spoon or spatula
• Aluminum foil (optional, for covering)

Instructions

1. Preheat your oven to 375°F (190°C). Grease your casserole dish lightly with olive oil or nonstick spray.
2. Prep the vegetables: Wash and chop all your vegetables into bite-sized pieces. If using frozen veggies, thaw and pat dry. For extra flavor, try roasting your broccoli and cauliflower for 10 minutes beforehand.
3. Sauté the aromatics: In your medium skillet, heat olive oil over medium heat. Add diced onion and sauté for 3-4 minutes until soft. Add minced garlic and cook for 1 additional minute, until fragrant.
4. Combine the filling: In a large mixing bowl, add cooked rice or quinoa, chickpeas, sautéed onion and garlic, all your chopped vegetables, and baby spinach. Toss together until well mixed.
5. Make the creamy sauce: In a separate bowl, whisk together milk, Greek yogurt, vegetable broth, Italian seasoning, salt, and pepper. Stir in half of the shredded cheese.
6. Assemble the casserole: Pour the creamy sauce over the veggie mixture. Stir until the vegetables are evenly coated.
7. Transfer to casserole dish: Spread the veggie mixture evenly into your prepared casserole dish. Sprinkle the remaining cheese over the top.
8. Add the topping: In a small bowl, mix breadcrumbs with 1 tablespoon olive oil and a pinch of salt. Sprinkle evenly over the casserole.
9. Bake the casserole: Place the dish in the oven and bake uncovered for 30-35 minutes, or until the top is golden and the casserole is bubbling at the edges.
10. Garnish and serve: Let the casserole cool for 5-10 minutes. Sprinkle fresh parsley on top before serving.

Pro Tip: For a creamier, cheesier casserole, try adding a layer of Vegan Bechamel Sauce between the veggie and breadcrumb layers!

Tips & Variations

• Swap the veggies: Substitute or add vegetables like mushrooms, green beans, peas, or corn. This recipe is a great way to use up whatever is in season.
• Make it vegan: Use plant-based milk, vegan cheese, and vegan yogurt or sour cream. Check out our Soy Free Vegan Recipes if you have allergies or dietary restrictions.
• Gluten-free version: Substitute the breadcrumbs with gluten-free panko or crushed gluten-free crackers.
• Protein boost: Add cubed tofu, tempeh, or more beans for a higher-protein meal.
• Add a sauce: For extra flavor, layer in some tomato sauce, pesto, or try our Vegetable Alfredo Recipes for creamy inspiration.
• Make ahead: Assemble the casserole up to a day in advance, cover tightly, and refrigerate. Bake when ready to serve, adding 5-10 minutes to the baking time if cold.
• Freeze for later: This casserole freezes well! Cool completely, wrap tightly, and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.
