Learn how to make this cheesy Brussels sprouts Instant Pot recipe to enjoy as a side dish for family dinner, Thanksgiving or Christmas. It's somewhere between a creamy brussels sprouts casserole and an au gratin bake and is very easy to make!
Wash the Brussels sprouts and trim the ends off. Cut them in halves but leave the small ones whole as they won't need as much cooking. Set aside.
1.3-1.5 lb Brussels sprouts
Pour the cream into the Instant Pot and add the garlic and onion powders, salt and pepper. Add the Brussels sprouts and ¼ cup of water and stir through gently.
1 cup light or whipping cream, 1 teaspoon garlic powder, 1 teaspoon onion powder, 1 teaspoon salt, ¼ teaspoon pepper, ¼ cup water
Secure and lock the lid. Set to Pressure Cook/Manual and adjust the time to ZERO minutes on HIGH. That's right, zero minutes simply means that majority of cooking will happen while the Instant Pot is coming to pressure. If you like soft Brussels sprouts OR you are using whole, unhalved sprouts, set to 1 minute on HIGH.
Once the timer is done, release the pressure immediately using the quick release. Remember that the Brussels sprouts will continue to cook if the pot remains on natural release. You may get away with 1 minute on NPR, but as it gets more than 2 minutes, we found our Brussels sprouts got too soft.
Open the lid. At a first glance, it will look like the cream curdled but don't worry, simply stir the sprouts into the sauce and it will melt back in.
If you plan to broil the cheese in the oven, preheat it on the highest broil setting while the sprouts are cooking. Move the rack up closer to the broil. Transfer the cooked Brussels sprouts and the sauce to a casserole dish and sprinkle all over with cheese. Pop under the hot broil for 5 minutes or so. If you don't want to use the oven, simply stir the grated cheeses into the Brussels sprouts while still in the pot on Keep Warm setting. Stir to melt and combine.
1 cup Cheddar cheese, 1 cup Parmesan cheese
Serve with chopped chives or parsley on top.
