Ingredients

Ingredient Quantity Notes
Broccoli florets 2 cups Fresh or frozen
Carrots 1 cup Thinly sliced
Zucchini 1 cup Diced
Red bell pepper 1 medium Diced
Yellow onion 1 small Chopped
Garlic cloves 3 Minced
Olive oil 2 tablespoons For sautéing
All-purpose flour 3 tablespoons For thickening sauce

Shredded cheddar cheese 1 ½ cups Or vegan cheese
Breadcrumbs ½ cup For topping
Parmesan cheese ¼ cup Optional, for topping
Dried thyme 1 teaspoon Or fresh
Salt and pepper To taste

Equipment

  • Large skillet or frying pan
  • Medium saucepan
  • Mixing bowl
  • 9×13-inch casserole dish
  • Wooden spoon or spatula
  • Measuring cups and spoons
  • Whisk

Instructions

  1. Preheat your oven to 375°F (190°C). Lightly grease your casserole dish with olive oil or cooking spray.
  2. Prepare the vegetables. Wash and chop the broccoli, carrots, zucchini, bell pepper, and onion into bite-sized pieces. Mince the garlic cloves.
  3. Sauté the veggies. Heat 2 tablespoons of olive oil in a large skillet over medium heat. Add the onion and garlic first, cooking until fragrant and translucent, about 3 minutes.
  4. Add the carrots, broccoli, zucchini, and bell pepper to the skillet. Sprinkle with dried thyme, salt, and pepper. Cook for about 5-7 minutes, stirring occasionally, until the vegetables soften but still have some bite.
  5. Make the creamy sauce. In a medium saucepan, melt 2 tablespoons of butter or olive oil over medium heat. Whisk in the flour and cook for 1-2 minutes to form a roux.
  6. Slowly add the milk while whisking vigorously to avoid lumps. Continue stirring until the sauce thickens, about 4-5 minutes.
  7. Remove the sauce from heat and stir in 1 cup of shredded cheddar cheese until melted and smooth. Season with salt and pepper to taste.
  8. Combine veggies and sauce. Transfer the sautéed vegetables to a large mixing bowl. Pour the cheese sauce over the veggies and gently mix to combine everything evenly.
  9. Assemble the casserole. Pour the mixture into your prepared casserole dish and spread it evenly.
  10. Top the casserole with the remaining ½ cup cheddar cheese, breadcrumbs, and parmesan cheese (if using) for a crunchy golden crust.
  11. Bake for 25-30 minutes. The casserole should be bubbling around the edges and the topping nicely browned.
  12. Remove from oven and let it cool for 5-10 minutes before serving.

Tips & Variations

“For a gluten-free version, substitute the all-purpose flour with gluten-free flour and use gluten-free breadcrumbs.”

You can easily swap the vegetables based on what’s in season or what you have on hand. Try adding mushrooms, spinach, or sweet potatoes for different flavors and textures.

For a vegan casserole, use plant-based milk, vegan cheese, and olive oil instead of butter. This recipe also pairs well with cooked quinoa or brown rice stirred into the veggie mixture for added protein and heartiness.

Want to add a protein boost? Toss in cooked chickpeas, lentils, or tofu cubes before baking.

To keep things exciting, consider experimenting with herbs like rosemary, basil, or oregano instead of thyme. A pinch of smoked paprika or chili flakes can add a subtle kick.
