Gathering Your Ingredients for Garlic Butter Steak Bites with Creamy Mashed Potatoes

Alright, let’s get our mise en place ready! Having everything prepped makes this meal a breeze. Trust me, it’s worth the little bit of chopping upfront.

For the Garlic Butter Steak Bites

You’ll need about 1.5 pounds of sirloin steak, cut into nice, bite-sized cubes – think about an inch square. For that amazing garlic butter marinade, we’re grabbing 4 tablespoons of unsalted butter, all melted, and 4 cloves of garlic that you’ll want to mince up really fine. Then, we’ll add 1 teaspoon of dried rosemary, half a teaspoon of salt, and a quarter teaspoon of black pepper. That’s it! Simple, but oh-so-flavorful.

For the Creamy Mashed Potatoes

For the perfect creamy potatoes, grab about 1.5 pounds of Yukon Gold potatoes. These guys are the best for mashing because they’re so fluffy and buttery. Peel them and then cut them into quarters so they cook evenly. To make them super creamy, we’ll need half a cup of milk that’s been warmed up just a bit, 4 tablespoons of unsalted butter, and about a quarter cup of sour cream for that extra tang and richness. Of course, we’ll season them with salt and pepper to taste!

Step-by-Step Guide to Making Garlic Butter Steak Bites with Creamy Mashed Potatoes

Okay, let’s get this deliciousness happening! It’s actually way simpler than it looks. We’ll tackle the steak marinade and the potatoes at the same time to make things super efficient.

Marinating the Steak

First things first, let’s get that steak marinating so it can soak up all that yummy flavor. Grab a medium-sized bowl. Pour in your 4 tablespoons of melted unsalted butter. Then, toss in your 4 cloves of minced garlic – I like it pretty garlicky, so feel free to add more if you’re a garlic fiend like me! Add the 1 teaspoon of dried rosemary, half a teaspoon of salt, and that quarter teaspoon of black pepper. Give it all a good stir to combine. Now, add your 1.5 pounds of sirloin steak cubes to that bowl. Make sure every single piece gets coated nicely in that garlicky butter mixture. You can use your hands for this, it’s way easier! Once they’re all coated, pop a lid on the bowl or cover it with plastic wrap and let it hang out on the counter for at least 30 minutes. If you have more time, you can totally stick it in the fridge for a couple of hours, but 30 minutes is usually plenty for this recipe.

Preparing the Creamy Mashed Potatoes

While the steak is doing its thing, let’s get those potatoes going. Put your peeled and quartered 1.5 pounds of Yukon Gold potatoes into a medium pot. Cover them with cold water, and add a generous pinch of salt to the water – this is key for flavorful potatoes! Bring the water to a boil over medium-high heat, then reduce it a bit to maintain a steady simmer. You’ll want to cook them until they’re super tender, which usually takes about 15 to 20 minutes. You should be able to easily pierce them with a fork. Once they’re tender, drain them really, really well. Seriously, get all that water out! You can even let them sit in the colander for a minute or two to steam dry a bit. Put the drained potatoes back into the warm pot. Now, add your 4 tablespoons of unsalted butter, the quarter cup of sour cream, and the half cup of warm milk. Start mashing! I love using a potato masher for this, but a sturdy fork works too. Mash until they’re smooth and creamy, but don’t go crazy and over-mash them or they can get gluey. Taste them and add salt and pepper until they’re just right. Keep them warm while you finish the steak.

Cooking the Garlic Butter Steak Bites

Okay, the grand finale! Get a large skillet – cast iron is my favorite for this – and heat it over medium-high heat. You don’t need to add any extra oil because the butter from the marinade will do the trick. Once the pan is nice and hot, carefully add your marinated steak bites. Try not to crowd the pan; if you have too many, cook them in batches so they actually sear instead of steam. You want to cook them for about 2 to 3 minutes per side. This will give you a nice brown crust on the outside and keep them perfectly tender on the inside. For medium-rare, 2 minutes per side is usually perfect. Adjust the time slightly if you like them more or less done. Once they’re cooked, take them off the heat right away. You can even toss them with a tiny bit more melted butter and a sprinkle of fresh parsley if you’re feeling fancy!

Tips for Perfect Garlic Butter Steak Bites with Creamy Mashed Potatoes

Want your steak bites to be melt-in-your-mouth tender and your mashed potatoes perfectly smooth? I’ve got you covered with a few little tricks I’ve learned over the years!

Achieving Tender Steak

The biggest secret to tender steak bites is not overcrowding the pan! Seriously, give those steak cubes some breathing room so they can sear properly. If your pan isn’t big enough, just cook them in batches. You want that beautiful golden-brown crust, not a sad, grey, steamed cube. Also, keep an eye on the cooking time – overcooking is the enemy of tender steak, so pull them off the heat as soon as they hit your desired doneness. A meat thermometer is your friend here if you’re unsure!

Ensuring Creamy Mashed Potatoes

For the creamiest mashed potatoes, make sure you drain those boiled potatoes really, really well. Any extra water will just make them watery, and nobody wants that! When you’re mashing, don’t go overboard. Mash until they’re smooth and fluffy, but stop before they start looking gluey or wallpaper paste-like. Adding the warm milk and butter gradually also helps get that perfect, smooth texture without making them tough.

Delicious Variations and Serving Suggestions for Garlic Butter Steak Bites

Want to jazz up your steak bites? It’s so easy! For a little extra umami boost, try adding a splash of soy sauce or Worcestershire sauce to your garlic butter marinade – it’s a game-changer. Feel free to play around with the herbs too; fresh thyme or even a pinch of red pepper flakes can add a nice kick. And for serving? These steak bites and creamy mashed potatoes are pretty much a meal in themselves, but a simple side salad with a light vinaigrette or some steamed green beans would be absolutely perfect!

Storing and Reheating Your Garlic Butter Steak Bites

Got leftovers? Lucky you! Let your garlic butter steak bites and mashed potatoes cool down completely, then store them in separate airtight containers in the fridge. They’ll keep well for about 2-3 days. To reheat, I find the best way is to gently warm the steak bites in a skillet over low heat with a tiny splash of water or broth to keep them moist. For the mashed potatoes, just pop them in the microwave or a saucepan with a little extra milk or butter until they’re creamy and hot again. Avoid reheating the steak in the microwave if you can, it can make them a bit tough!

Frequently Asked Questions about Garlic Butter Steak Bites with Creamy Mashed Potatoes

Got questions? I’ve got answers! This garlic butter steak bites with creamy mashed potatoes recipe is pretty forgiving, but here are a few things people often wonder about.

Can I use a different cut of steak?

Absolutely! While sirloin is my favorite for its tenderness and flavor, you can totally use other cuts like ribeye, filet mignon, or even a nice strip steak. Just make sure it’s a cut that’s good for quick cooking. If you use a tougher cut, you might need to marinate it a bit longer, maybe an hour or so, to help tenderize it. Just cut it into those same 1-inch cubes!

How do I prevent the steak from becoming tough?

The biggest culprits for tough steak bites are overcooking and overcrowding the pan. Make sure your skillet is nice and hot before you add the steak, and give those cubes some space! Cook them in batches if needed. Aim for that perfect medium-rare to medium; it usually only takes 2-3 minutes per side. Once they’re done, take them off the heat right away. Letting the steak rest for just a couple of minutes after cooking can also help keep them super tender and juicy.

Can I make the mashed potatoes ahead of time?

You sure can! Mashed potatoes are actually pretty good for making ahead. Once they’re mashed and creamy, let them cool down, then store them in an airtight container in the fridge for up to 2 days. To reheat, I like to put them in a saucepan over low heat with a splash of milk or a bit more butter, stirring gently until they’re smooth and hot again. You can also microwave them, but keep an eye on them and stir halfway through so they don’t dry out.
