Equipment

  • Large mixing bowl – For combining ingredients
  • Large skillet – To sauté vegetables and prepare the sauce
  • Whisk – For mixing the sauce smoothly
  • 9×13 inch casserole dish – For baking
  • Measuring cups and spoons – For accuracy
  • Oven – Preheated to 375°F (190°C)
  • Knife and cutting board – To prep vegetables

Instructions

  1. Preheat your oven to 375°F (190°C) and grease your casserole dish lightly with oil or non-stick spray.
  2. Prepare the vegetables: Chop the broccoli, cauliflower, and carrots into bite-sized pieces. Dice the onion and mince the garlic.
  3. Sauté the aromatics: In a large skillet, heat the olive oil over medium heat. Add the onion and garlic and cook until translucent and fragrant, about 3-4 minutes.
  4. Add the vegetables: Toss in broccoli, cauliflower, and carrots. Sauté for 5-7 minutes until they start to soften but remain crisp.
  5. Make the sauce: Sprinkle the flour over the vegetables and stir well to coat. Slowly whisk in the milk, stirring constantly to avoid lumps. Continue cooking over medium heat until the sauce thickens, about 5 minutes.
  6. Season: Add salt, black pepper, dried thyme, and nutmeg. Stir to combine all flavors evenly.
  7. Combine and transfer: Pour the vegetable mixture into your prepared casserole dish. If using, sprinkle the grated cheese evenly on top.
  8. Add the topping: Sprinkle the bread crumbs over the casserole for a golden, crunchy finish.
  9. Bake: Place the casserole in the oven and bake for 25-30 minutes, or until the top is golden brown and bubbly.
  10. Rest and serve: Let the casserole cool for 5 minutes before serving to allow it to set and flavors to meld.

Tips & Variations

Tip: Use whatever vegetables you have on hand! Zucchini, bell peppers, mushrooms, or spinach can be excellent additions or substitutions.

For a vegan version, swap dairy milk for unsweetened almond or oat milk and use a plant-based cheese alternative or omit cheese entirely.

To add extra protein, consider mixing in cooked lentils, chickpeas, or tofu cubes before baking. For a Mediterranean twist, add sun-dried tomatoes and olives.

If you want to experiment further, try pairing this casserole with homemade bread or tortillas. You might enjoy the Vegan Flour Tortilla Recipe Easy, Soft, and Homemade or the Vegan Bread Maker Recipe for Soft and Delicious Loaves for perfect side options.
