Ingredient Guide

Steak
Go for sirloin or ribeye—both bring tenderness and great flavor. Sirloin is lean and cooks evenly, while ribeye adds richness thanks to its fat content. Dice the steak into uniform pieces to help them cook quickly and evenly.

Garlic
Fresh garlic is the backbone of the sauce. A quick sauté in butter brings out its flavor without making it too sharp. Want something milder? Roasted garlic is a great alternative.

Heavy Cream
Cream brings the body and silkiness to the sauce. If you want to lighten things up a little, you can use half-and-half, though the sauce will be a bit thinner.

Butter
Butter is essential here. It adds richness, helps sear the steak, and builds the base for the garlic cream. Stick with unsalted to better control the final salt level.

Parmesan Cheese
Parmesan adds a deep umami punch to the mashed potatoes. Always grate it fresh—pre-shredded options won’t melt smoothly and tend to be less flavorful.

Potatoes
Yukon Golds are ideal—they’re naturally creamy and have a buttery flavor that works beautifully in mashed potatoes. Russets will give you a fluffier texture if you prefer that.

Milk
Use warm milk to blend the mashed potatoes—it keeps the mixture hot and smooth. Whole milk adds richness, but lower-fat versions work too.

Salt & Pepper
Don’t skimp. These two basics are key for bringing out the full flavor of both the steak and the potatoes.

Olive Oil
Adding olive oil to the butter when searing steak increases the smoke point and helps get that gorgeous brown crust.

Fresh Herbs (Optional)
Garnish with parsley or chives to add a touch of freshness and color to this hearty dish.

Cooking Instructions

1. Cook the Potatoes
   Peel and cube the potatoes, then place them in a pot of salted cold water. Bring to a boil and simmer for 15–20 minutes or until they’re tender when pierced with a fork. Drain and return them to the pot to let excess moisture evaporate.

2. Mash with Flavor
   Add the butter, warm milk, and Parmesan to the hot potatoes. Mash until they’re creamy with a little texture left in. Season with salt and pepper. Cover and keep warm.

3. Sear the Steak
   Cut your steak into bite-sized chunks and pat dry. Season well with salt and pepper. In a hot skillet, heat the olive oil and a tablespoon of butter. Add the steak in a single layer—don’t overcrowd—and cook for 2–3 minutes per side until browned. Transfer to a plate and cover loosely with foil.

4. Build the Garlic Cream Sauce
   Lower the heat and add more butter to the same skillet. Stir in the minced garlic and cook for about 30 seconds until fragrant. Pour in the cream and scrape up the browned bits from the bottom of the pan. Simmer gently for 2–3 minutes until slightly thickened.

5. Bring It All Together
   Return the steak (and any juices) to the skillet. Stir to coat the bites in the sauce and let everything heat through for another 1–2 minutes. Adjust seasoning if needed.

6. Plate and Serve
   Spoon mashed potatoes into bowls or plates, then top with creamy garlic steak bites. Sprinkle with fresh herbs or extra Parmesan, if desired.

Pro Tip: Make sure the cream is at room temperature before adding it to the pan—cold cream can separate or curdle when it hits high heat.

Smart Tips, Custom Options & Easy Swaps

Helpful Tips

Nutritional Insights

Though it leans into comfort food territory, this meal offers a good balance of protein, carbohydrates, and healthy fats.

Steak adds iron and protein, while potatoes bring energy-boosting complex carbs. Parmesan offers flavor in small amounts, allowing you to use less salt. Want a lighter version? Reduce the butter and cream or substitute in lighter dairy products.

Mashed cauliflower is an easy swap to reduce carbs. And if you’re watching sodium, use unsalted butter and limit added cheese or use a low-sodium alternative.

Frequently Asked Questions

1. Can I prepare this in advance?
Yes. You can make both the steak and mashed potatoes ahead of time. Store them separately in airtight containers, and reheat gently with a splash of cream or milk to keep the texture smooth.

2. What’s the best cut of steak for this?
Sirloin is great for its affordability and tenderness. Ribeye brings more flavor thanks to its marbling. Avoid leaner cuts unless you’re marinating first to tenderize.

3. Can I cook steak from frozen?
It’s best to thaw completely before searing. Frozen steak won’t brown properly, and excess moisture can make it steam instead of sear.

4. How do I make this low-carb?
Replace the mashed potatoes with mashed cauliflower and ensure your sauce doesn’t use flour or thickeners. The steak and cream sauce are naturally low in carbs.

5. How do I avoid overcooking the steak?
Don’t overcrowd the pan and cook in batches if necessary. Sear for just a few minutes per side. The goal is a golden exterior and a tender interior.

6. Is this recipe scalable for a crowd?
Absolutely. Just cook the steak in multiple batches to avoid crowding the skillet. Keep the cooked steak warm in a low oven while finishing the rest.

7. How should leftovers be stored?
Refrigerate any leftovers in airtight containers for up to 3 days. When reheating, add a splash of cream or milk to revive the sauce and keep the potatoes creamy.
