Preparation
1. Boiling vegetables
In a deep pot, boil the carrots for 10 minutes in water salted with 2 teaspoons of salt. Once the 10 minutes have passed, add the cauliflower to the water.Boil for 3 minutes, or after the cauliflower changes colors and, immediately after, remove it from the hot water (do not overcook, they have to be tender but firm). Set aside in a large bowl.
2. Sauteing vegetables
Heat half the butter over very low heat in an oven-safe skillet.Add the onion and garlic and cook for 3 minutes or until the onions become translucent. Stir often to cook uniformly. Add the carrot and cauliflower and increase heat to medium. Cook and stir until all the ingredients are heated through.Remove the vegetables from the skillet.
3. Making sauce
Heat the other half of the butter in the skillet over low heat. Sift the flour into the pan, and stir until there is no more "raw" flour in sight. Add the milk and mix. Simmer until the milk turns into a creamy sauce (think ranch dressing).Add the parsley, parmesan cheese, and half of the cheddar cheese and stir until the cheese has melted. Season with salt and black pepper to taste. Remove from the heat.
4. Broiling
Return the vegetables to the skillet and stir to coat them with the sauce. Sprinkle the vegetables with the remaining cheddar cheese. Cook under the broiler until the cheese melts or browns (depending on your preference).
Top tips
- Gluten-free version: If you follow a gluten-free diet, you can use cornstarch in place of flour. The flavor and texture are a bit different, but the main flavors remain the same.
- To save leftovers: Place them in an air-tight container and place them in the refrigerator, where they will last for about 48 hours. To reheat the leftovers, place them on a baking sheet pan lined with parchment paper, and reheat them in the oven over low temperature.
- Individual servings: If you have 6 small skillets or baking pans, you can bake them in individual servings.
- Adding broccoli: You can make a healthy broccoli cauliflower carrot casserole recipe by substituting broccoli for half the cauliflower. You can make the dish with just broccoli too, and the same process and cooking times apply.
- How to boil: The trick to cauliflower that is not mushy is simply to cook them for a short period of time, which I do in this dish by parboiling them, then broil to brown. The result is cauliflower cooked just enough, but that still has some bite.
Serving suggestions
We love this cheesy cauliflower casserole as a simple, quick brunch, or mid-afternoon dish. I served it with just bread (try it with cheddar bread rolls!), but this makes a perfect side dish for BBQs with any of your favorite salads.
Roasted vegetables are great served as a side dish to grilled meat, or as a light meal with some rustic bread. It goes great with air-fried chicken, stuffed chicken breast, and my brined chicken roast.
If you loved this dish, you might want to try this cauliflower cheese soup too, or for another lighter casserole, try this slow cooker ratatouille.
