Brussels sprouts are one of those vegetables that people either love or hate. I find that the secret to making the best brussels sprouts is roasting them with plenty of sliced mushrooms, salt, and lemon juice. The mushrooms add an amazing umami flavor and the salt and lemon juice both help to reduce the natural bitterness of the brussels sprouts while adding a bright citrus flavor.

This recipe is very easy to make because everything gets added to a casserole dish to roast in the oven until fork-tender. If you think you don’t like brussels sprouts try this recipe because they are savory, full of flavor, and don’t taste grassy at all!

Recipe Ingredients

  • Brussels sprouts – They should be firm with a bright green color. Avoid soft ones or if they look wilted with yellow leaves.
  • Mushrooms – I used cremini mushrooms, but white button mushrooms can be used as well! The mushrooms, as they cook, release their juices which adds so much flavor to the brussels sprouts.
  • Lemon – The lemon juice adds a strong citrus flavor and brightness to this dish. I add the juice of half a lemon, but feel free to add more if you like!
  • Olive oil – Use good quality olive oil for this recipe, It’s used to cook the brussels sprouts and to give a nice savory flavor.

How To Make Brussels Sprouts with Mushrooms

All ingredients, measurements, and instructions are in the recipe card at the bottom of this post.

Step 1. Rinse and cut the bottoms off the brussels sprouts as well as remove any bad-looking outer leaves. Then cut them in half lengthwise.

Step 2. Into a 2-quart casserole dish add the brussels sprouts, sliced mushrooms, lemon juice, olive oil, salt, and black pepper. Mix until combined.

Step 3. Cover the dish with a lid. This is important so the brussels sprouts do not dry out before they become tender. Bake for 40 – 45 minutes or until the brussels sprouts are fork-tender.

Step five. Optionally, you can remove the lid and increase the temperature to 425 degrees, and then roast the brussels sprouts for another 15 – 20 minutes or until they are your desired level of crispiness. Serve warm with your favorite main dishes. Enjoy!
