Beef Tenderloin & Balsamic Steak Sauce
with Chive Mashed Potatoes & Roasted Asparagus
- Milk
If nothing says “date night” like a juicy steak, then this dish is the equivalent of getting down on one knee. Here, melt-in-your-mouth beef tenderloin (the same cut as filet mignon!) is seared and then drizzled with a rich balsamic pan sauce (cue the swoons). On the side, there’s crisp roasted asparagus and creamy chive-flecked mashed potatoes. No matter who you cook this for, we have a good feeling they’ll be quite smitten.

Cooking Steps
• Adjust rack to middle position and preheat oven to 425 degrees. Wash and dry produce. • Dice potatoes into ½-inch pieces. Mince chives. Trim and discard woody bottom ends from asparagus; cut stalks crosswise into 1-inch pieces.
• Place potatoes in a large pot with enough salted water to cover by 2 inches. Bring to a boil and cook until very tender, 15-20 minutes. Reserve ½ cup potato cooking liquid, then drain. • Return potatoes to pot and add sour cream, half the chives, and 1 TBSP butter (2 TBSP for 4 servings). Mash, adding splashes of reserved cooking liquid as needed, until smooth and creamy. Season with salt and pepper. Cover to keep warm.
• While potatoes cook, toss asparagus on a baking sheet with a drizzle of olive oil, salt, and pepper. Roast on middle rack until tender and lightly browned, 10-12 minutes.
• Meanwhile, pat beef* dry with paper towels; season all over with salt and pepper. Heat a drizzle of oil in a large pan over medium-high heat. Add beef and cook to desired doneness, 4-7 minutes per side. • Remove from heat; transfer beef to a plate to rest. Wipe out pan.
• Add demi-glace, half the vinegar (all for 4 servings), and ¼ cup water (1⁄3 cup for 4) to pan used for beef over medium-high heat. Bring to a simmer and cook until thickened, 2-3 minutes. • Remove from heat and stir in 1 TBSP butter (2 TBSP for 4) until melted. Season with salt and pepper.
• Divide beef, asparagus, and mashed potatoes between plates. Drizzle beef with sauce. Garnish with remaining chives and serve.
Beef is fully cooked when internal temperature reaches 145°.

Reviews from our home cooks
Previously I had trouble cooking these to the doneness we prefer. This time I pounded them with a meat tenderizing hammer so they weren't so thick, and they came out perfect for us. The asparagus was very fresh and delicious. We all just wished there was more of it. The potatoes were really good too especially with a little of the sauce we put on the steak. I don't especially like prepping chives, but these added a nice background flavor, so it was worth it. We all loved everything about this meal.
This is my #1 favorite of all the meals I've cooked so far! The meat was super tender. The Balsamic steak sauce was tasty. The asparagus was so fresh and terrific roasted. I love mashed potatoes any way you fix them. The meal was easy to prepare.
I don't know why, but the hello fresh way of making mashed potatoes is by far the best way for creamy, quick, easy mashed potatoes that aren't instant mash. The asparagus came out almost buttery, the Beef was super tender and the sauce a great compliment. But I could eat those potatoes every day. They are just that good. A little tip for others, if the chives wilt a lil, just pop em in some cool water for 10 minutes and then go to cut em. They crisp back up and make for easier cutting then. Oh, and if you plan to cut the potatoes ahead of time, put them in water so they don't oxidize and discolor.
This was an excellent meal. I liked everything, asparagus, mashed potatoes. the steak. The Balsamic steak sauce was excellent. Hello Taste recipes for sauces so far have always been excellent. Thank you.
Really enjoyed the balsamic steak sauce. Nice to have asparagus in a meal. Did not take long to make.
The meal was worth the mess it created 😂 The beef was especially tender, juicy, and flavorful. I am also a sucker for mashed potatoes with chives.
The sauce was easy to make. The recipe called for white balsamic, but dark balsamic was included instead... That was indeed too much oomph for the meat. Good meat. The asparagus didn't last long enough. I cooked it on Monday night. My bad. I roasted the potatoes instead of mashing. My bad. My picky eater loved the sour cream and chives as a sauce, though, so really nice job on ingredients and recipes, for the most part. This recipe was easier to assemble than some others, so good work there. I guess it's really hard to ship green veggies, so you don't need my feedback there. My kids are generally well pleased and they weren't disappointed this time, except by comparison to your normal excellence. I think it might have been the missing white balsamic, honestly...
The meat was flavorful and tender, the sauce was a perfect match for the meal. Always enjoy the flavoring for the mashed potatoes and the baked asparagus was excellent.
It was really good, the beef tenderloin was super tender and I somehow cooked it perfectly medium. I'll definitely order it again, it's well worth the premium price.
I really like this meal, as evidenced by the fact that I got two in this box. The beef was so tender and tasty, and the asparagus was perfect.
