Instant Pot® Cheesy Broccoli and Cauliflower Bake

01 / WHAT YOU NEED

Ingredients

cooking spray 1 (12 ounce) package frozen cauliflower and broccoli 1 (10.75 ounce) can condensed cream of mushroom soup 1 cup sour cream 1 ½ cups shredded sharp Cheddar cheese, divided ¼ cup minced onion ½ teaspoon garlic powder salt to taste

02 / HOW TO MAKE IT

Let's cook.

Step 1

Start by tossing the frozen cauliflower and broccoli into your Instant Pot along with a bit of water. Seal the lid and set it to high pressure—don’t worry about setting a timer since it only takes a few minutes to come to pressure. Once the pressure is up, carefully quick-release it following your Instant Pot’s instructions. When it’s safe to open, scoop the veggies out with a slotted spoon and transfer them to a greased 8-inch square baking dish. Dump out any leftover water from the pot.

Step 2

Next, hit the sauté button on the Instant Pot and add the condensed soup, sour cream, ¾ cup of cheddar cheese, chopped onion, garlic powder, and a pinch of salt. Stir everything together until the cheese melts and the mixture gets nice and creamy, about 3 to 5 minutes. Pour this cheesy sauce over the veggies in the baking dish, then sprinkle the remaining cheddar on top.

Step 3

Pop the dish into a 400°F oven (preheat it while you’re prepping) and bake for about 20 to 30 minutes, or until the cheese is bubbly and golden. If you want a little extra browning on top, switch the oven to broil for a couple of minutes—just keep an eye on it so it doesn’t burn. Let it cool slightly before digging in!

Good to know.
