Chef's Cooking Tips

- Use fresh or frozen broccoli and cauliflower, but cut them into similar-sized pieces for even cooking.
- If you prefer a thicker bake, reduce the liquid slightly before pressure cooking.
- Let the pressure release naturally for a few minutes to keep the vegetables tender but not mushy.

Step 1

Ad the frozen cauliflower and broccoli to your Instant Pot along with a bit of water. Close the lid, set it to high pressure, and let it come up to pressure—which usually takes about 10 to 15 minutes. Once it’s ready, carefully do a quick release of the pressure, then open the lid. Use a slotted spoon to transfer the veggies to a greased 8-inch square baking dish, and dump out any leftover water from the pot.

Step 2

Switch your Instant Pot to the sauté setting. Stir in the condensed soup, sour cream, ¾ cup of cheddar cheese, chopped onion, garlic powder, and a pinch of salt. Keep stirring until the cheese melts and the mixture is nice and creamy, about 3 to 5 minutes. Pour this cheesy sauce over the vegetables in the baking dish, then sprinkle the remaining cheddar on top.

Step 3

While you’re doing this, preheat your oven to 400°F (200°C). Pop the baking dish in the oven and bake until the cheese is melted and the top is golden brown, around 20 to 30 minutes. If you want a bit more color, you can finish it off under the broiler for a couple of minutes—just watch it closely so it doesn’t burn.

Serving Advice

Serve this bake as a main dish with a crisp green salad or crusty bread. It also pairs well as a side with grilled chicken or roasted pork. Sprinkle extra cheddar on top before serving for a melty finish.

Keeping Leftovers Fresh

Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, warm gently in the microwave or oven until heated through. Avoid freezing, as the texture of the vegetables may change.
