Meatloaves with Creamy Mushroom Sauce
plus Garlic Mashed Potatoes & Roasted Green Beans
- Milk
- Wheat
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 green beans 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 (middle and top 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 green beans if necessary.
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, then 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.) Roast on top rack for 5 minutes.
Remove sheet from oven; carefully toss green beans on empty side of baking sheet with a drizzle of oil, salt, and pepper. Roast on top rack until meatloaves are cooked through and green beans are browned and tender, 12-15 minutes. (For 4 servings, leave meatloaves roasting; toss green beans on a second baking sheet and roast on middle rack.)
While everything roasts, trim and thinly slice mushrooms (skip if your mushrooms are pre-sliced!). 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 (⅓ cup water for 4 servings). Bring to a boil, then 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 green beans between plates. Spoon sauce over meatloaves. Sprinkle with scallion greens and serve.

Review summary
Updated on Sep 2026- Flavor: The mushroom sauce is the undisputed star — rich, savory, and delicious on both the meatloaves and the mashed potatoes 🍲.
- Ease of prep: The recipe comes together relatively quickly, though several reviewers noted it takes longer than the suggested time, especially when making mashed potatoes from scratch.
- Suggestions: Add a splash of cornstarch slurry if the sauce won't thicken, and season the meatloaf mix generously — some found it mild and wished for more herbs or a touch of ketchup on top. A few also found the green beans needed extra seasoning or a slightly longer cook time.
- Leftovers: This meal reheats well and tastes just as good the next day, making it a satisfying choice for planned leftovers.
- Portions: A few reviewers felt the meatloaf portion was on the smaller side and suggested using a full 16 oz of ground beef for a heartier result.
Reviews from our home cooks
The portions were a good size, it was really filling. The mushroom sauce on top was a great addition to the meal, and the mashed potatoes were delicious as well. The meatloaves tasted like they were well-seasoned, as did everything on the plate. It was a perfect dinner meal.
This was our favorite this week. The meat cooked up tender, the green beans were delicious, and the mashed potatoes were creamy and well seasoned, although I added some shredded swiss cheese into the potatoes to make them even creamier. And if I did this again, I'd make the mushroom sauce a bit saucier with more beef broth, and add some milk or a couple of tablespoons to the meat mixture to make the meatloaves even moister.
This was absolutely delicious. The meat loaf and mushroom gravy was my favorite but the potatoes and green beans were delicious as well. Wish this would come up more often on the menu. I would order it every week
Great comfort food! Tasty meatloaves with a creamy mushroom sauce on top. Potatoes were delicious. The green beans were tasty and little crisp.
My favorite part of this dish was the meatloaf and mushroom sauce!!! The potatoes and green beans were good as well but that meatloaf was OMG good! I'm learning so much with the recipe cards and really beefing up my culinary skills!!!!
My family always loves the meatloaf meals, and the mushroom sauce on this meal really kicked up the flavor a notch. The mashed potatoes were straight forward to make and had good mix ins to keep the flavors up. We have struggled with the green beans, however, because half of the time they are already wilted when they get to us and often could use some more seasoning after cooked.
This was outstanding! I wasn't quite sure how to feel about a meatloaf with mushroom sauce since I am so used to BBQ or ketchup or a combo of both. This was delicious and I will be getting this one again when I see it. Well done!
This was AMAZING!!! The only thing that would have made this dish any better is if there was a little more of the mushroom sauce for the meatloaves / potatoes. Our family loved this one!!!
I can't think of anything that I like least. The creamy mushroom sauce was great tasting and easy to make. It definitely enhances the taste of the meal. I especially like the added garlic to the potatoes. Yummy.
Salisbury Steak would be more accurate title. Meatloaf is usually one large loaf that is sliced and is tomato-based. I added bacon and garlic-herb spice mix to the green beans to punch up the flavor and added them to the tray at same time as meat. Cremini mushrooms are better than white button mushrooms but it still made a nice sauce. Garlic powder is boring. Prefer the spice mixes that Blue Apron has and used my own herbs/spices for this meal.
