Ingredients

  • Broccoli and Cauliflower Florets: You’ll need a pound of each.
  • Baby Carrots: I use baby carrots, but you can use whole carrots cut into 1-2 inch sections.
  • Butter: For the cheese sauce.
  • Garlic: Minced or pressed.
  • Cornstarch: Just a couple of tablespoons to thicken the sauce.
  • Heavy Cream: You can use half-and-half or milk, but the sauce won’t be as thick and rich.
  • Italian Seasoning
  • Salt and Pepper
  • Chili Powder and Nutmeg: To flavor the cheese sauce.
  • Italian Blend Cheese: You can also use other cheeses like cheddar, Gruyere, or a different blend.
  • Panko: For the crunchy topping. Feel free to substitute pork-rind Panko.

How To Make A Vegetable Casserole

  1. Pre-Cook the Vegetables: Boil all the vegetables in a large pot for 8 minutes.
  2. Make the Cream Sauce: Melt the butter in a skillet, stir in the garlic, and whisk in cornstarch; add cream, and boil until thickened.
  3. Add Cheese and Seasonings: Remove from the heat, stir in Italian seasoning, salt, pepper, chili powder, nutmeg, and cheese until melted.
  4. Assemble the Casserole: Layer cheese sauce, veggies, and more sauce in the baking dish; season with salt and pepper as you go. Top with Panko crumbs.
  5. Bake at 400˚F for 20 minutes until bubbly, then rest for 10 minutes to set.

Make Ahead Method

To make the casserole ahead, I suggest pre-cooking the veggies and sauce and storing them separately in the fridge for up to 2 days before using. Assemble and bake the casserole the day you want to serve it.

Recipe Tips

  • Choose Fresh Vegetables: Selecting fresh and crisp vegetables will enhance the flavors of the casserole.
  • Don’t Overcook the Vegetables: Boiling the vegetables until just fork-tender will keep them from getting mushy in the final bake.
  • Season to Taste: Adjust seasonings like salt, pepper, or herbs to suit your taste preferences.
  • Shredded Cheese: Experiment with different types of cheese to find your perfect flavor combination.
  • Allow to Rest: Letting the casserole rest for a few minutes after baking will allow it to set, making serving easier.
