• Black Pepper: Freshly cracked pepper adds heat and character, especially on the steak bites.
• Garlic Powder: Provides a mellow, savory undertone without overpowering the other flavors.
• Neutral Oil: Use something like canola or vegetable oil for a high smoke point that sears steak beautifully.
• Golden Potatoes: Yukon Golds are starchy and buttery, perfect for creamy mashed potatoes.
• Whole Milk: Brings lushness and a velvety consistency to the mash.
• Sharp Cheddar Cheese: Melts in for a tangy richness that makes the potatoes irresistible.
• Unsalted Butter: Adds depth and a silky texture to the mashed potatoes.
• Beef Broth: Scrapes up all the browned bits for a truly savory pan sauce.
• Steak Sauce: A dash makes the sauce extra robust and brings traditional steakhouse flavor.
• Champagne Vinegar: Lifts the sauce with a bit of acidity—you’ll really taste the difference.
• Dijon Mustard: Adds a tiny kick and rounds out the sauce beautifully.
• Worcestershire Sauce: Gives depth and umami that ties everything together.
• Kosher Salt & Black Pepper (to taste): Adjust seasoning so every bite is completely dialed in for your tastebuds.
• Chopped Parsley (for garnish): A scattering of fresh parsley adds color and a pop of freshness at the end.

How to Make Steak Bites with Mashed Potatoes

Step 1: Prepare the Potatoes

First up, grab your golden potatoes and give them a good peel. Cut them into generous quarters so they’ll cook evenly. Bring a large pot of salted water to a boil, then add in those potatoes. Simmer until they’re fork-tender, usually around 25 to 30 minutes. This step is key to achieving ultra-creamy mashed potatoes that are the perfect bed for your steak bites.

Step 2: Mash and Mix

Once the potatoes are tender, drain them well and return them to the pot. Right away, start mashing so they stay hot and fluffy. Add the unsalted butter and milk in batches, mixing until lush and smooth. Finally, fold in the sharp cheddar cheese so it melts and weaves rich, tangy flavor through every bite. Keep the potatoes warm while you turn your attention to the steak.

Step 3: Cube and Season the Steaks

For those signature Steak Bites with Mashed Potatoes, cut your NY strips into bite-sized cubes—as uniform as possible for even cooking. Toss the cubes with a drizzle of neutral oil, a hearty sprinkle of kosher salt, black pepper, and a dusting of garlic powder. This simple seasoning brings out the absolute best in each tender steak bite.

Step 4: Sear the Steak Bites

Heat a cast iron skillet over high heat and add a little beef tallow or more neutral oil. Once the skillet is just about smoking, add your steak cubes in a single layer. Sear for about 3 to 3.5 minutes per side, letting them develop a gorgeous brown crust. When they hit around 120°F for rare or 130°F for medium-rare, pull them from the pan and let them rest for 10 minutes, giving all those juices time to settle.

Step 5: Create the Pan Sauce

Turn those steak drippings into gold! Pour beef broth into your hot skillet and scrape up all those caramelized bits. Add steak sauce, champagne vinegar, Dijon mustard, Worcestershire, and a bit more black pepper. Simmer for about 10 minutes until it thickens into a glossy, intensely savory sauce. Taste and season with salt as needed—it should be bold and delicious.

Step 6: Serve and Savor

Spoon a generous portion of mashed potatoes onto each plate. Top with a hearty pile of steak bites, then drizzle with a generous amount of that beautiful pan sauce. Finish with a flourish of chopped parsley, and your Steak Bites with Mashed Potatoes are ready to wow everyone at the table!

How to Serve Steak Bites with Mashed Potatoes

Garnishes

To make your Steak Bites with Mashed Potatoes extra special, sprinkle plenty of chopped fresh parsley over the top. A tiny finishing pinch of flaky sea salt or a light dusting of cracked black pepper can add a little extra pop that looks impressive, too. If you want a little richness, a knob of butter melting into the mash is pure heaven.

Side Dishes

This dish is hearty on its own, but a crisp green salad with a tangy vinaigrette balances its richness. Roasted asparagus, garlicky green beans, or even charred broccoli make fresh, vibrant additions that keep things feeling bright and well-rounded.

Creative Ways to Present

If you’re entertaining, try serving Steak Bites with Mashed Potatoes in shallow bowls with extra pan sauce pooled around the edges. For a fun twist, pipe the mashed potatoes in a swirl and nestle the steak bites on top. Or, serve everything family-style so guests can build their own perfect plates—this dish feels right at home, however you present it!

Make Ahead and Storage

Storing Leftovers

If you have leftovers, store the steak bites and mashed potatoes separately in airtight containers. The potatoes will last up to four days in the fridge, while the steak bites are best enjoyed within two to three days for peak tenderness. Save extra pan sauce in a small jar so it’s ready to reheat and pour over just before serving.

Freezing

Mashed potatoes freeze quite well! Spread them in a freezer-safe container and press plastic wrap directly onto the surface to prevent freezer burn, then seal. The steak bites can also be frozen, but be aware that reheating may lead them to cook further, so keep them slightly under if you’re batch-prepping. Store the pan sauce separately in a freezer bag or small container.

Reheating

For best results, reheat mashed potatoes in a saucepan with an extra splash of milk or a little butter, stirring gently until warmed through. Reheat steak bites quickly in a hot skillet to avoid overcooking, or use short bursts in the microwave. Warm the pan sauce until steaming, then serve everything together—your Steak Bites with Mashed Potatoes will taste nearly as good as fresh!

FAQs

Can I use different cuts of steak for Steak Bites with Mashed Potatoes?

Absolutely! While NY strip offers great flavor and tenderness, sirloin, ribeye, or even tenderloin all work well. Just adjust the cooking time and be sure to cut the steak into even pieces for best results.

How do I keep my mashed potatoes from getting gluey?

The trick is not to overwork them. Mash just until smooth, and add the butter and milk gradually. A potato masher or ricer gives the fluffiest texture—skip the food processor, as that can turn even golden potatoes into a gummy consistency.

Can I make Steak Bites with Mashed Potatoes ahead of time for guests?

Yes, mashed potatoes can be made ahead and gently reheated with a little extra milk or butter. Sear steak bites just before serving for best texture, but you can pre-cut and season the steak ahead of time. Pan sauce can also be made ahead and warmed up when you’re ready to serve.

What if I don’t have champagne vinegar for the pan sauce?

No worries! You can substitute white wine vinegar or even a splash of apple cider vinegar for a similar effect. Champagne vinegar just brings a delicate, bright note, but other vinegars will work in a pinch.

How do I make this recipe gluten-free?

Steak Bites with Mashed Potatoes are already gluten-free, but always double-check your steak sauce, Dijon mustard, and Worcestershire ingredients, as some brands can contain gluten. Opt for certified gluten-free versions if you or your guests are sensitive.
