Step-by-Step Instructions
Step 1: Preheat & Prepare
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with butter or olive oil.
Tip: If using frozen veggies, no need to thaw—just add 5 extra minutes to baking time.
Step 2: Blanche the Vegetables
Bring a large pot of salted water to boil. Add cauliflower and broccoli florets, blanch for 3 minutes, then immediately transfer to an ice bath or rinse with cold water to stop cooking.
Personalization Tip: For more bite, reduce blanching time to 2 minutes. For softer textures, go 4.
Step 3: Make the Cheese Sauce
In a saucepan over medium heat, combine heavy cream, sour cream, minced garlic, nutmeg, salt, and pepper. Stir until warm (do not boil), then whisk in 1 cup shredded cheddar, ¼ cup Parmesan, and a ½ teaspoon of paprika. Stir until smooth and cheesy.
Chef’s Note: Taste the sauce before baking—adjust seasoning as needed.
Step 4: Combine in Baking Dish
Layer the cooked veggies into the greased dish. Pour cheese sauce evenly over the top. Sprinkle with remaining cheddar and Parmesan. Crumble bacon across the top for that irresistible crunch.
Step 5: Bake Until Golden
Bake uncovered for 25–30 minutes or until the cheese is bubbling, and the top has a golden hue.
Pro Tip: Broil for the last 2–3 minutes if you love crispy cheese edges!
Step 6: Cool Slightly
Allow the casserole to rest for 5–10 minutes before serving. This helps the texture set and enhances flavor intensity.
Step 7: Garnish and Serve
Optional but elevated: Sprinkle with chopped fresh parsley or chives for color and freshness.

Common Mistakes to Avoid
❌ Overcooking the vegetables: This leads to mushy texture. Blanch briefly for best results.
❌ Using pre-shredded cheese: Contains anti-caking agents, which prevent smooth melting. Shred fresh for optimal creaminess.
❌ Skipping rest time: Cutting into it immediately makes the sauce watery. Give it time to thicken up.
❌ Overcrowding the pan: Spread veggies evenly to ensure proper baking and flavor integration.

FAQs
❓ Can I make this casserole ahead of time?
Absolutely. Assemble the entire dish, cover, and refrigerate up to 24 hours before baking. Add 5–7 extra minutes to bake time if used straight from the fridge.
❓ Can I use only cauliflower or only broccoli?
Yes, using one vegetable works just fine. We recommend adjusting cooking time slightly (broccoli may cook quicker).
❓ How do I make it vegetarian?
Omit the bacon or use a plant-based alternative like tempeh bacon or smoky mushrooms.
❓ Which cheese melts best?
Sharp cheddar offers bold flavor and good meltability. For smoother texture, mix with mozzarella or havarti.
❓ What if my sauce is too thin?
Let it rest after baking; it will thicken upon cooling. Next time, decrease cream slightly or add a teaspoon of cornstarch pre-bake.
