    From the Test Kitchen

    To give this dish a sophisticated lift, we’re dolloping a rich, flavorful compound butter (simply butter combined with balsamic-marinated cipolline onions) onto savory pan-seared steaks. Sides of mashed potatoes and roasted brussels sprouts round out the plate on a comforting note.

    Steaks & Cipolline Onion Butter with Mashed Potatoes & Brussels Sprouts
    Title
    • 2 Steaks
    • 2 cloves Garlic
    • ½ lb Brussels Sprouts
    • ¾ lb Potatoes
    • 2 Tbsps Crème Fraîche
    • 1 Tbsp Apple Cider Vinegar
    • 1 oz Salted Butter
    • 1 oz Balsamic-Marinated Cipolline Onions
    Prepare the ingredients
    1 Prepare the ingredients

    Remove the butter from the refrigerator to soften. Preheat the oven to 450°F. Fill a medium pot 3/4 of the way up with salted water; cover and heat to boiling on high. Wash and dry the fresh produce. Medium dice the potatoes. Peel and roughly chop 2 cloves of garlic. Cut off and discard the stem ends of the brussels sprouts; halve lengthwise. Roughly chop the onions.

    Cook & mash the potatoes
    2 Cook & mash the potatoes

    Add the diced potatoes and chopped garlic to the pot of boiling water and cook 16 to 18 minutes, or until tender when pierced with a fork. Turn off the heat. Drain thoroughly and return to the pot. Add the crème fraîche; season with salt and pepper. Using a fork or potato masher, mash to your desired consistency. Taste, then season with salt and pepper if desired. Cover to keep warm.

    Roast & dress the brussels sprouts

    Meanwhile, place the halved brussels sprouts on a sheet pan. Drizzle with olive oil and season with salt and pepper; toss to coat. Arrange in an even layer. Roast 14 to 16 minutes, or until browned and tender when pierced with a fork. Remove from the oven. Evenly top with the vinegar; carefully stir to coat.

    Cook the steaks
    4 Cook the steaks

    Meanwhile, pat the steaks dry with paper towels; season with salt and pepper on all sides. In a medium pan (nonstick, if you have one), heat a drizzle of olive oil on medium-high until hot. Add the seasoned steaks. Cook, turning occasionally, 8 to 10 minutes for medium-rare (125°F), or until browned and cooked to your desired degree of doneness.* Transfer to a cutting board; let rest at least 5 minutes. 

    *The USDA recommends a minimum safe cooking temperature of 145°F for steak. Cook the steaks an additional 2 to 3 minutes to achieve this. 
    Consuming raw or undercooked meat, poultry, fish, seafood or eggs may increase your risk of foodborne illness.

Top the steaks and potatoes with the cipolline onion butter. Enjoy!
