How to Make This Garlic Butter Steak Bites and Mash

Here’s your step-by-step guide to making this meal. Take your time, follow each step, and you’ll end up with something truly special.

Step 1: Prep the Steak

Start with quality steak. Trim off any excess fat and cut into 1-inch bite-sized pieces. Pat them dry with paper towels—this helps get that golden crust when searing. Season generously with salt and pepper. Let the steak rest at room temperature while you get everything else ready. Cold meat won’t sear as well.

Step 2: Boil the Potatoes

Peel and cut your potatoes into evenly sized chunks. Add them to a large pot of cold, salted water. Bring it to a boil and cook until fork-tender, about 15 minutes. If you want a hint of garlic flavor, toss a peeled garlic clove into the pot.

Step 3: Sear the Steak Bites

Heat a large skillet over medium-high heat. Add olive oil—you want it shimmering but not smoking.
Working in batches, add steak bites in a single layer. Don’t crowd the pan! Let them sear for 2 minutes without moving them to get a nice crust. Then flip and cook for another 1-2 minutes for medium-rare.
Transfer the steak to a plate and tent loosely with foil.

Step 4: Make the Garlic Butter Sauce

Lower the heat to medium. In the same pan, add unsalted butter. Once melted, toss in the minced garlic. Sauté for 30 seconds—just until fragrant, not browned.
Return the steak bites to the pan, toss to coat in the garlic butter, and cook for another 1 minute just to warm through. Sprinkle with chopped parsley.

Step 5: Mash the Potatoes

Drain the potatoes and return them to the pot. Add butter, heavy cream, salt, and pepper to taste. Mash until smooth and creamy. If they’re too thick, add a little more warm cream or milk.

Step 6: Plate and Serve

Spoon a generous portion of mashed potatoes onto each plate. Top with the garlic butter steak bites and drizzle some of that delicious garlic butter sauce over everything.

Substitutions

If you’re missing an ingredient or want to switch things up, here are some options to keep the recipe flexible.

For the Steak

• Chicken breast or thighs work well if you’re not a beef eater. Use the same method.
• Pork tenderloin is another tender, juicy option.
• Tofu for a vegetarian take. Make sure to press it well and crisp it in the pan before adding garlic butter.

For the Garlic Butter

• Ghee instead of butter if you’re going for a clarified, slightly nutty flavor.
• Herb-infused oils, like rosemary or thyme, can enhance the flavor without using butter.

For the Mash

• Cauliflower mash if you want a lower-carb option.
• Sweet potatoes for a sweeter, more nutrient-dense version.
• Use plant-based milk and butter for a dairy-free mash.

The goal is to make it your own while keeping the essence of this delicious comfort meal intact.

Best Side Dishes for Garlic Butter Steak Bites and Mash

Looking to round out your meal? These sides pair perfectly with the richness of the steak bites and mash:

1. Garlic Roasted Broccoli

Oven-roasted with olive oil and garlic, it adds a healthy crunch and balances out the meal.

2. Caesar Salad

The crisp romaine and creamy dressing are a refreshing contrast to the hearty steak and potatoes.

3. Buttered Green Beans with Almonds

Serving and Presentation Tips

There’s nothing quite like serving a dish that looks as good as it tastes. Whether it’s a casual weeknight meal or something special for guests, presentation adds that extra wow factor.

Make It Look Effortless (Even If You Spent 30 Minutes on It!)

• Serve on a large, shallow platter. Spread the creamy mashed potatoes as the base, then arrange the steak bites over the top. Drizzle any leftover garlic butter sauce right before serving for a glossy finish.
• Garnish with chopped parsley or fresh thyme. That pop of green brightens the dish and makes it look fresh and inviting.
• Sprinkle flaky sea salt just before serving. It adds a little texture and an elevated flavor kick.
• Use warm plates. Warm plates help keep the steak bites and mash hot longer, making the dish feel extra cozy.

If you’re serving family-style, don’t forget a big spoon so everyone can help themselves. It’s a crowd-pleaser!

Tips and Tricks to Make This Recipe Even Better

This dish is already packed with flavor, but these little tips can take it over the top.

Start with Room Temperature Steak

Cold steak straight from the fridge won’t sear properly. Take it out 20-30 minutes before cooking. This allows the meat to cook more evenly and gives you that beautiful crust.

Pat the Steak Dry

Moisture is the enemy of a good sear. Use paper towels to blot the steak pieces before seasoning and searing. Dry steak equals crispy, golden edges.

Don’t Crowd the Pan

If you try to cook too many steak bites at once, they’ll steam instead of sear. Cook in batches, and make sure there’s plenty of space between each piece.

Use a Cast Iron Skillet

If you have one, grab it! Cast iron holds heat incredibly well, giving your steak bites that restaurant-quality crust.

Warm the Cream and Butter for the Mash

Adding cold dairy products to hot potatoes cools them down and makes the mash gluey. Warm your cream and melt the butter before mixing them in for a silky, smooth mash.

Common Mistakes to Avoid

Even simple recipes can trip you up if you’re not careful. Here are a few mistakes to watch for—and how to fix them.

Overcooking the Steak

Steak bites cook fast—about 2-3 minutes per side. If you leave them in the pan too long, they’ll turn tough and chewy. Pull them out while they’re still a little pink inside. They’ll continue cooking in the garlic butter sauce.

Burning the Garlic

Garlic burns quickly and turns bitter. After adding butter to the pan, let it melt gently over medium heat, then add the garlic. Keep it moving, and don’t let it go longer than 30 seconds.

Lumpy Mashed Potatoes

If you don’t mash the potatoes while they’re hot, they’ll get gluey. Use a potato ricer or masher while they’re warm, and don’t overwork them. Too much mixing releases starch and makes them gummy.

How to Store It

Garlic Butter Steak Bites and Mash makes great leftovers! Follow these tips to keep everything tasting fresh.

Storing Leftovers

• Store the steak bites and mashed potatoes separately in airtight containers.
• Keep them in the fridge for up to 3 days.
• Reheat steak bites gently in a skillet over low heat with a little extra butter to prevent drying out.
• Reheat the mashed potatoes with a splash of cream or milk in a saucepan, stirring until smooth.

Freezing

• Mashed potatoes can be frozen! Cool completely, transfer to a freezer-safe bag or container, and freeze for up to 1 month. Thaw overnight in the fridge and reheat with cream.
• I don’t recommend freezing the steak bites—they’re best fresh, but if you must, wrap them tightly and freeze for up to 1 month. Thaw and reheat gently.

FAQ

1. Can I make this recipe ahead of time?

You can prep ahead! Cut and season the steak bites earlier in the day. Make the mashed potatoes and reheat them just before serving. For best results, sear the steak bites and make the garlic butter sauce fresh.

2. What’s the best cut of steak for steak bites?

Sirloin is my go-to because it’s tender, flavorful, and affordable. Ribeye or tenderloin will give you an even more luxurious bite. Avoid tougher cuts like chuck roast unless you marinate them.

3. Can I use pre-minced garlic from a jar?

You can, but fresh garlic makes a big difference in this recipe. The flavor is sharper and more aromatic. If you’re in a pinch, jarred garlic will work—use about 1 teaspoon per clove.

4. How can I make this dish dairy-free?

Swap the butter for olive oil or dairy-free butter, and use plant-based milk for the mashed potatoes. Make sure to taste and adjust the seasoning as needed.

5. What can I serve instead of mashed potatoes?

If you want to skip the mash, try serving the steak bites with rice, quinoa, or roasted vegetables. They all soak up the garlic butter sauce beautifully.
