Garlic Butter Steak Bites and Potatoes Ingredients

Here's what goes into this easy skillet Garlic Butter Steak Bites and Potatoes dinner, and why each one matters.

See Recipe Card Below This Post For Ingredient Quantities

  • Olive oil: Used in two stages, first for cooking the potatoes and again for searing the steak. It has a higher smoke point than butter alone, which helps you get that golden crust without burning anything.
  • Kerrygold garlic and herb butter sticks: This is the star of the recipe. It melts into the pan and coats everything in rich, garlicky flavor. Kerrygold's version is especially creamy and flavorful, but a homemade garlic herb butter or another store brand works fine if you can't find it.
  • Yukon Gold potatoes: These have a naturally buttery texture and a thin skin, so they cook up creamy on the inside and golden on the outside without falling apart. Cut them into bite-sized cubes so they cook evenly.
  • Sirloin steak: Sirloin is a great cut for steak bites because it's lean enough to sear beautifully but still tender and flavorful. Cut into even cubes so every piece cooks at the same rate.
  • Salt: Seasons both the potatoes and the steak separately, so every layer of the dish has flavor built in.
  • Pepper: Adds a gentle warmth and pairs naturally with the garlic butter.
  • Garlic powder: Used on both the potatoes and the steak to deepen that savory, garlicky flavor throughout the whole dish.

how to make Garlic Butter Steak Bites and Potatoes

Here's a look at the full process, step by step.

  1. Prepare the skillet: Heat a large cast iron skillet over medium heat for a couple of minutes before adding anything. A properly heated pan makes a real difference in how evenly everything cooks.
  2. Cook the potatoes: Add 1 tablespoon of olive oil and 1 tablespoon of garlic herb butter to the skillet. Once the butter melts, add the Yukon Gold potatoes. Season with ½ teaspoon garlic powder, ½ teaspoon salt, and ½ teaspoon pepper, or a little more to your taste.

  1. Simmer the potatoes: Lower the heat to medium-low, cover the skillet, and let the potatoes cook for 10 to 12 minutes, stirring occasionally. You're looking for fork-tender potatoes with golden, slightly crispy edges. Keep an eye on the heat and adjust if things are browning too fast.
  2. Season the steak: While the potatoes cook, toss the steak bites with the remaining ½ teaspoon each of salt, pepper, and garlic powder. Getting this done ahead of time means the steak is ready to go straight into the pan.
  3. Sear the steak bites: Once the potatoes are done, push them to one side of the skillet or remove them temporarily. Add the remaining tablespoon of olive oil and tablespoon of garlic herb butter to the empty side of the pan, and raise the heat to medium-high. Add the steak bites and sear for 3 to 4 minutes per side until browned and cooked to your preferred doneness. If your pan feels crowded, cook the steak in batches so every piece sears properly instead of steaming.

  1. Combine and coat: Lower the heat back to medium-low. Add extra garlic butter if you'd like, let it melt, then toss the steak and potatoes together until everything is evenly coated and glossy. This is the moment the whole dish comes together.
  1. Taste and serve: Give it a quick taste and adjust the seasoning if needed. Serve hot and enjoy.

Substitutions and Swaps

No Kerrygold garlic and herb butter? You can make your own by mixing softened butter with minced garlic and fresh or dried herbs like parsley, thyme, or rosemary. A plain compound butter with Garlic Butter Steak Bites and Potatoes will work just as well.

For the potatoes, red potatoes or baby potatoes are a great swap if you don't have Yukon Golds. They have a similar creamy texture and hold their shape well in the skillet.

For the steak, ribeye bites will be richer and more marbled, while tenderloin bites will be extra buttery and soft. Sirloin is the best balance of flavor and budget, but you've got options depending on what's available or what you prefer.

If you want a little extra depth of flavor, a small splash of Worcestershire sauce stirred in at the end adds a nice savory note without overpowering the Garlic Butter Steak Bites and Potatoes.

EQUIPMENT for Garlic Butter Steak Bites and Potatoes

You don't need much for this recipe, which is part of what makes it such a great weeknight go-to.

Cast iron skillet: This is the key piece of equipment. Cast iron holds heat evenly and gets hot enough to give the steak that beautiful sear. A large skillet (12 inches) gives you room to cook everything without crowding.

Knife and cutting board: For cutting the potatoes and steak into even, bite-sized cubes. Even cuts mean even cooking, so take a little time here.

Measuring spoons: For portioning the oil, butter, and seasonings accurately.

Storage Tips

Leftovers keep well in an airtight container in the refrigerator for up to 3 days. To reheat, warm them in a skillet over medium-low heat with a small pat of butter to bring back the glossy coating. The microwave works too, though the potatoes can get a little soft.

For best results, don't store the Garlic Butter Steak Bites and Potatoes in sauce or broth, just keep them as-is so they reheat cleanly.

Expert Tips

Don't skip preheating the pan. A cold skillet leads to uneven cooking and no sear on the Garlic Butter Steak Bites and Potatoes. Give it a couple of minutes over medium heat before you add anything.

Cook in batches if needed. Crowding the pan traps steam and prevents browning. If your skillet is full, cook the Garlic Butter Steak Bites and Potatoes in two rounds for the best crust.

Watch the heat with butter. Butter burns faster than oil, so keep a close eye on the temperature, especially when you increase the heat for the steak. Combining it with olive oil helps, but medium-high is the ceiling here.

Let the steak rest just a minute. Even bite-sized pieces benefit from a brief rest before tossing. It helps keep them juicy.

Season in layers. Seasoning the potatoes and steak separately (rather than all at once at the end) means every component is properly flavored from the start.

FAQ

What are the common mistakes in garlic butter?

The biggest one is burning the butter. Butter has milk solids that brown quickly over high heat, especially in a cast iron skillet. Always combine it with olive oil to raise the smoke point, and don't walk away from the pan when the heat is up. Another common mistake is under-seasoning - Garlic Butter Steak Bites and Potatoes needs a good amount of salt to really shine.

What is the best cut of Garlic Butter Steak Bites and Potatoes?

Sirloin is a top choice because it's flavorful, affordable, and holds up well to high-heat searing. Ribeye gives you more fat and richness if you want something more indulgent. Tenderloin is the most tender option but tends to be pricier. For everyday Garlic Butter Steak Bites and Potatoes, sirloin hits the sweet spot. Family tip: if you're feeding kids, tenderloin bites are extra soft and easy to eat.

What goes well with steak bites and potatoes?

A simple green salad, roasted veggies, or a side of crusty bread all pair beautifully. If you want to make the meal feel a little more special, serve with a side of creamy horseradish sauce or a drizzle of extra garlic herb butter. Steak bites and mashed potatoes are also a cozy variation worth trying on a cold night.

How to cook the best Garlic Butter Steak Bites and Potatoes?

Start with a well-seasoned, properly heated cast iron skillet. Pat the steak dry before adding it to the pan so it sears instead of steams. Use a combination of butter and oil, and don't flip too early - let each side develop a proper crust before turning. Finish with extra Garlic Butter Steak Bites and Potatoes melted over the top for maximum flavor. Steak bites are forgiving, but the sear is everything.
