Cooking Steps
-
Adjust rack to top position and preheat oven to 425 degrees. Drop cream cheese (in packet) into a glass of warm water to soften. Wash and dry produce.
-
Cut potatoes into ½-inch rounds.
-
Toss potatoes on a baking sheet with a drizzle of oil, salt, and pepper. Roast on top rack until browned and tender, 20-25 minutes.
-
Pat steak* dry with paper towels; season all over with salt and pepper.
-
Heat a drizzle of oil in a medium pan over medium-high heat. Add steak and sear, turning occasionally, until browned all over, 4-8 minutes.
-
Turn off heat; transfer steak to a second baking sheet. Roast on middle rack until cooked to desired doneness, 8-10 minutes. Wipe out pan.
-
Transfer steak to a cutting board; let rest at least 8 minutes.
-
Meanwhile, dice tomato into ½-inch pieces. Lightly crush croutons in their bag. Trim and thinly slice mushrooms (skip if your mushrooms are pre-sliced!). Quarter lemon.
- In a small bowl, whisk together cream cheese, sour cream, Worcestershire sauce, and ¼ cup water (⅓ cup for 4 servings) until thoroughly combined. Set aside.
-
In a large bowl, combine arugula, tomato, Parmesan, and croutons (you’ll toss salad with dressing in Step 6).
-
Heat a drizzle of oil in same pan used for steak over medium-high heat. Add mushrooms, half the Italian Seasoning (all for 4 servings), salt, and a pinch of pepper. Cook, stirring occasionally, until mushrooms are browned and slightly crispy, 2-4 minutes.
-
Add cream cheese mixture and 1 TBSP butter (2 TBSP for 4) to pan with mushrooms. Bring to a simmer; cook, stirring constantly, until slightly thickened, 30-60 seconds. TIP: If sauce is too thick, add a splash of water.
-
Remove from heat; cover to keep warm.
-
To bowl with salad, add a drizzle of olive oil, juice from two lemon wedges, salt, and pepper (large drizzle of olive oil and juice from four lemon wedges for 4 servings). Toss to combine.
-
Thinly slice steak against the grain.
-
Divide steak, roasted potato rounds, and salad between plates in separate sections. Spoon mushroom sauce over steak. Serve with remaining lemon wedges on the side.

Reviews from our home cooks
The potatoes and sauce in this was really good, but the steak was not--it was really tough and chewy and hard to eat. I would get this again but with a different cut of beef.
We really liked the flavorful mushroom sauce. Tasty and hearty meal for reasonable calorie count.
One of my favorites. The sauce on the steak was so good and the potatoes were amazing
Delicious. Love the sauce. I cook my potatoes in the air fryer. Saves time
Steak was very good and large portions, sauce was yummy!
Was great! Wasn't the biggest fan of the salad but the meal was on point!
More steak would be nice but perfect other than that
Delicious but took quite a bit of time to prepare.
This was delicious! Lots of different parts but really enjoyed it
I knew the potatoes needed something else so I added some garlic. Salad was bland with just oil and lemon, I toss in a little Caesar dressing. Tomato was barely ripe and pale. Steak and sauce were fabulous.
