plus Garlic Mashed Potatoes & Roasted Brussels Sprouts
- Wheat
- Milk
This delicious dish is the definition of umami. Not sure if you’ve ever experienced the “fifth taste?” After one bite, you’ll totally understand the obsession. Mini meatloaves are baked to perfection, then draped in a supremely savory mushroom sauce. The luxurious loaves are served alongside crispy roasted Brussels sprouts and garlicky mashed potatoes—aka more things to catch any runaway ’shroom sauce. Plus, the whole shebang cooks up in a flash (just 35 minutes!). What are you waiting for?

Cooking Steps
• Adjust rack to top position (top and middle positions for 4 servings) and preheat oven to 425 degrees. Wash and dry produce. • Dice potatoes into ½-inch pieces. Trim and thinly slice scallions, separating whites from greens; mince whites. Trim and halve Brussels sprouts lengthwise. • Place potatoes in a large pot with enough salted water to cover by 2 inches. Bring to a boil and cook until tender, 15-20 minutes. • Reserve ½ cup potato cooking liquid; drain and return potatoes to pot.
• While potatoes cook, in a large bowl, combine beef*, panko, scallion whites, half the garlic powder (you’ll use the rest later), and 1 TBSP water (2 TBSP for 4 servings); season generously with salt and pepper. • Form mixture into two 1-inch-tall loaves (four loaves for 4).
• Place meatloaves on one side of a lightly oiled baking sheet. (TIP: Line sheet with foil first for easier cleanup.) Toss Brussels sprouts on empty side with a drizzle of oil; season generously with salt and pepper. • Roast on top rack until meatloaves are cooked through and Brussels sprouts are browned and tender, 15-20 minutes. (For 4 servings, use 2 baking sheets; roast meatloaves on middle rack and Brussels sprouts on top rack.) TIP: If sprouts finish first, remove from sheet and continue roasting meatloaves.
• While everything roasts, trim and thinly slice mushrooms. • Heat a drizzle of oil in a medium pan over medium-high heat. Add mushrooms; season with salt and pepper. Cook, stirring, until softened, 2-4 minutes. • Stir in stock concentrate and ¼ cup water (1⁄3 cup water for 4 servings). Bring to a boil; reduce to a low simmer. Cook until slightly thickened, 2-3 minutes. • Turn off heat. Stir in half the sour cream (you’ll use the rest in the next step) and 1 TBSP butter (2 TBSP for 4) until melted and combined. Season with salt and pepper.
• Heat pot with drained potatoes over low heat; add 1 TBSP butter (2 TBSP for 4 servings), remaining sour cream, and remaining garlic powder. • Mash until smooth and creamy, adding splashes of reserved potato cooking liquid as needed. Season with salt and pepper.
• If necessary, reheat pan with sauce over low heat; stir until warmed through. • Divide meatloaves, mashed potatoes, and Brussels sprouts between plates. Spoon sauce over meatloaves. Sprinkle with scallion greens and serve.

Reviews from our home cooks
Meatloaves need more flavor, hard sear in pan before baking might give it what it needs, this was a very 'mushy' dinner as it really only had the soft textures. The Brussel sprouts needed more time in the oven, at a lower temperature might be better because the centers had not fully softened but the leaves were getting crispy. Mushroom sauce was delicious and coupled with the garlic potatoes, that's what made this 3 stars and not 2. Eating dinner like this shouldn't feel like a chore, or an obligation, the point is to enjoy eating this meal, but this one was leaning towards the former
This was incredible! The creamy mushroom sauce is a really winner! But it was only this delicious because we added more spices. We LOADED up the meatloaves with extra seasoning. Steak seasoning, a bit of crushed red pepper as well as onion powder. I also added the steak seasoning to the mushroom gravy. Please consider adding more spices to this meal, then it will be AMAZING!
I would give this 3.75⭐ Mashed potatoes were really good. I did like how quick the mini meatloaves get done, but not enough flavor. The mushroom sauce was fabulous. The brussel sprouts were super and plentiful. I have learned, from previous time, (for our preference) to quarter instead of halve and parboil for 1 min before roasting. Still not overdone. I think it would be better to update instructions to roast longer or parboil. Raw brussel sprouts just too bitter.
The meatloaf was excellent! The brussels sprouts were good as well, nothing special, but good. The standout was the garlic mashed potatoes - creamy, garlicky, and downright delicious! The only thing I didn't like was the sauce - too salty.
The mushroom sauce is incredible! It pulled the whole dish together. If I ever try to replicate this recipe, I would at least double the sauce proportions so there's enough to cover the meatloaf and potatoes. Overall a great, hearty recipe, especially on a cold day!
We make homemade meatloaf all the time at home but this meal was great as a single serve meal for 2. The seasonings were great, the mushroom sauce was absolutely delicious and the roasted Brussel Sprouts were so good.
This was so good. It combines a few of my favorite HelloFresh staples: mashed potatoes with sour cream mixed in, a surprisingly savory and very simply made meat portion, and one heck of a sauce (this mushroom sauce has to be up there in my top 10). Overall, I was just so happy with how this turned out.
Meat loaves are tasty and very filling. Mushroom sauce was wonderful and something I have never had on a meatloaf. Our first taste of roasted Brussels Sprouts and really liked them..items are all so fresh.
Really enjoyed the meat loafs. They were so easy to make and delicious with the mushroom cream sauce over the top!
This was very good. Im not a meatloaf fan but this was FIRE. Loved the creamy mushroom sauce. Definitely will make this was again and again. ❤️🔥
