How to Make Creamy Winter Vegetable Casserole
Preheat Oven: Start by preheating your oven to 375 °F (190 °C). This ensures even baking for your casserole.
Blanch Vegetables: In a large pot, boil cauliflower, broccoli, and carrots for 3-4 minutes. Drain and set aside, keeping them vibrant and slightly crunchy.
Saut Aromatics: Heat olive oil in a skillet and saut the chopped onion and minced garlic for about 5 minutes, until they are translucent and fragrant.
Add Remaining Veggies: Introduce the diced potatoes and chopped Brussels sprouts to the skillet. Stir for 5-7 minutes until they are slightly softened but still firm.
Mix Vegetables: In a large mixing bowl, combine your blanched vegetables with the saut ed onion and garlic mixture. Toss well to mix all the flavors.
Prepare Sauce: In a separate bowl, whisk together the heavy cream, vegetable broth, thyme, rosemary, salt, and pepper. Pour this luscious sauce over the vegetable mix and stir until fully coated.
Assemble Casserole: Transfer the vegetable mixture into a greased 9 13 inch baking dish. Sprinkle shredded cheddar cheese on top and, if desired, add breadcrumbs for an extra crunch.
Bake Covered: Cover the dish with foil and bake it in the preheated oven for 30 minutes. This will help meld all the flavors together beautifully.
Bake Uncovered: Remove the foil after 30 minutes and bake for an additional 15-20 minutes until the cheese is golden and bubbly, creating a tempting top layer.
Cool Before Serving: Let your casserole rest for about 5 minutes before serving. This allows the sauce to thicken a bit for a perfect serving texture.
Optional: Drizzle with a splash of lemon juice for an added layer of freshness.
