Preparing Cheddar Broccoli Cauliflower Gratin
Creating a delicious Cheddar Broccoli Cauliflower Gratin may sound daunting, but it’s easier than you think! Follow my step-by-step guide, and you’ll serve up a side dish that will impress everyone at the table. Let’s dive right in!
Preheat and Prepare the Baking Dish
Before you start cooking, it’s essential to set the stage. Preheat your oven to 375°F. While it warms up, grab a 2 ½ quart baking dish or a 9x9 inch baking pan. Give it a good spray with nonstick cooking spray or brush it with olive oil. This little step ensures that your scrumptious gratin doesn’t stick and makes cleanup a breeze!
Assemble Your Vegetables
Now it's time to focus on those veggies. You'll need 4 cups of broccoli florets, 4 cups of cauliflower florets, and 3 medium sliced carrots. This colorful mix not only boosts the dish’s nutritional value but also adds a lovely rustic look that’s perfect for serving guests. Feel free to use fresh or frozen veggies, but if you opt for frozen, make sure to thaw and drain them well.
Make the Cheese Sauce from Scratch
Here comes the fun part! In a large skillet or pot, melt 2 tablespoons of salted butter over medium heat. Add in a couple of tablespoons of flour, and mix it all together until it’s smooth. Gradually whisk in 2 ⅓ cups of unsweetened almond milk (or your milk of choice), taking care to avoid lumps. Bring this mixture to a gentle boil, then reduce the heat and simmer until it thickens—like a velvety gravy. Stir in garlic powder, salt, and lots of freshly ground black pepper. Finally, toss in 8 ounces of sharp cheddar cheese and ⅓ cup of parmesan cheese, stirring until they melt beautifully into that creamy sauce.

Combine Cheese Sauce and Vegetables

Add Topping and Bake to Perfection
While your gratin is baking, let’s prepare the topping. In a medium bowl, mix together ¾ cup of panko breadcrumbs with 1 tablespoon of melted butter. This crispy topping is what takes your Cheddar Broccoli Cauliflower Gratin to the next level! After your initial 30 minutes of baking, remove the foil, sprinkle the breadcrumb mixture over the top, and bake uncovered for an additional 20-30 minutes until they turn golden brown and the veggies are fork-tender.
When it’s all done, serve this cheesy delight to your friends and family and watch their faces light up with joy!

Bring mixture to a boil, then reduce heat to low and simmer for a few minutes stirring every so often, until the sauce thickens up similar to a gravy.

If the sauce is too thin, stir in another tablespoon of flour.
- Next add in sharp cheddar cheese and parmesan cheese and stir until completely melted into the sauce. Taste and add more salt and pepper, if desired. A fairly salty cheese sauce is best!
