Step-by-Step Instructions

Step 1: Prepare the Vegetables
Preheat your oven to 375°F (190°C). Wash and cut the broccoli and cauliflower into bite-sized florets. Pro tip: Keep the florets uniform in size to ensure even cooking.
Step 2: Blanch the Vegetables
Bring a large pot of salted water to a boil. Blanch the broccoli and cauliflower for 2-3 minutes until slightly tender but still crisp. Immediately transfer to an ice bath to stop the cooking process and preserve the vibrant colors.
Step 3: Prepare the Topping
In a bowl, mix the gluten-free breadcrumbs, grated Parmesan, olive oil, garlic powder, and dried thyme. This crispy topping will add a delightful texture contrast to your casserole.
Step 4: Assemble the Casserole
Drain the vegetables well and arrange them in a 9×13 inch baking dish. Pour the gluten-free cheese sauce evenly over the vegetables, ensuring all florets are coated.
Step 5: Add the Topping and Bake
Sprinkle the breadcrumb mixture over the top of the casserole. Bake for 25-30 minutes, or until the top is golden brown and the cheese sauce is bubbling around the edges.
Step 6: Rest and Serve
Allow the casserole to rest for 5-10 minutes before serving. This resting period helps the cheese sauce to set slightly, making it easier to serve and enhancing the overall texture.

Common Mistakes to Avoid
- Overcooking the vegetables: Blanch them just until tender-crisp to prevent a mushy texture.
- Using regular breadcrumbs: Always double-check that your breadcrumbs are certified gluten-free to maintain the integrity of the dish.
- Skipping the resting period: Letting the casserole rest ensures easier serving and better texture.
- Not seasoning adequately: Don’t be shy with salt and pepper; proper seasoning enhances the natural flavors of the vegetables.
Storing Tips for the Recipe
To keep your casserole fresh and delicious:
- Store leftovers in an airtight container in the refrigerator for up to 3 days.
- Reheat in the oven at 350°F (175°C) for 15-20 minutes to maintain the crispy topping.
- For meal prep, assemble the casserole but don’t bake it. Cover tightly and refrigerate for up to 24 hours before baking.
- Freeze individual portions for up to 2 months. Thaw overnight in the refrigerator before reheating.
