Ingredients:
- 1 lb sirloin steak, cut into bite-sized pieces
- 2 tbsp vegetable oil
- 4 cloves garlic, minced
- 3 tbsp unsalted butter (for steak bites)
- 1 tsp dried thyme
- 1 tsp dried rosemary
- Salt and pepper to taste (for steak bites)
- 2 lbs potatoes, peeled and cubed
- 1/2 cup milk
- 4 tbsp unsalted butter (for mash)
- Salt and pepper to taste (for mash)
Preparing the Potatoes for Mashing
Let’s get started with the creamy mashed potatoes, as they’ll need some time to boil. Start by peeling your 2 pounds of potatoes. You can use a vegetable peeler for this, or if you prefer, a sharp knife. Once peeled, give them a good rinse under cold water to remove any excess starch. Now, cut them into roughly uniform, bite-sized cubes. This is important because it ensures that all the potato pieces cook evenly. If some pieces are much larger than others, you’ll end up with a mixture of mushy and undercooked potatoes, and nobody wants that! Aim for cubes that are about 1 to 1.5 inches in size.
Place all your cubed potatoes into a large pot. Cover them generously with cold water. The water should be at least an inch above the potatoes. Add a good pinch of salt to the water; this seasons the potatoes from the inside out as they cook, which makes a world of difference in the final flavor of your mash. Bring the pot to a rolling boil over high heat. Once boiling, reduce the heat to medium-high, cover the pot partially (leaving a small gap for steam to escape), and let them simmer. You’ll want to cook them until they are fork-tender. This usually takes about 15-20 minutes, but it’s best to check by piercing a potato cube with a fork or a paring knife. It should slide in easily with no resistance.
Cooking the Delicious Steak Bites
While the potatoes are bubbling away, we can focus on the star of the show: the steak bites. Pat your sirloin steak pieces thoroughly dry with paper towels. This step is crucial for achieving a beautiful sear and preventing the steak from steaming rather than browning. Season the steak generously on all sides with salt and pepper. Don’t be shy with the seasoning; it really brings out the flavor of the beef.
Heat the 2 tablespoons of vegetable oil in a large skillet or cast-iron pan over medium-high heat. You want the oil to be shimmering but not smoking. Carefully add the seasoned steak bites to the hot skillet in a single layer. It’s important not to overcrowd the pan. If you have too many pieces, they will steam instead of searing, and you’ll miss out on that lovely crispy exterior. Cook the steak in batches if necessary. Sear the steak bites for about 2-3 minutes per side, or until they have a nice brown crust and are cooked to your desired doneness. For medium-rare, aim for an internal temperature of around 130-135°F (54-57°C). Remember, they will continue to cook slightly after being removed from the heat.
Once the steak bites are seared and cooked to your liking, remove them from the skillet and set them aside on a clean plate. Don’t wipe out the skillet just yet; all those browned bits are full of flavor! Reduce the heat to medium. Add the 3 tablespoons of unsalted butter to the skillet. Once the butter has melted and is starting to foam, add the 4 cloves of minced garlic. Sauté the garlic for about 30-60 seconds until it’s fragrant, being careful not to burn it. This will infuse the butter with a wonderful garlic aroma.
Now, sprinkle in the 1 teaspoon of dried thyme and 1 teaspoon of dried rosemary. Stir them into the garlic butter for about 30 seconds until their aromas are released. Return the seared steak bites to the skillet, along with any accumulated juices from the plate. Toss the steak bites in the herby garlic butter to coat them evenly. Let them simmer gently in the sauce for another minute or two, allowing the flavors to meld and the steak to finish cooking if needed. This quick finishing step ensures every bite is infused with deliciousness.
Finishing the Creamy Mashed Potatoes
While the steak bites are having their flavor bath, check on your potatoes. Once they are tender, drain them thoroughly in a colander. Allow them to steam dry in the colander for a minute or two. This helps to remove excess moisture, which is key to achieving fluffy mashed potatoes. Return the drained potatoes to the warm pot they were cooked in.
Add the 4 tablespoons of unsalted butter to the hot potatoes. Let the butter melt for a moment. Now, pour in the 1/2 cup of milk. For the creamiest mash, it’s best to warm the milk slightly before adding it, but room temperature milk works too. Begin extract mashing the potatoes. You can use a potato masher for a chunkier texture or a ricer or food mill for a super smooth mash. Gradually incorporate the butter and milk as you mash. Season the mashed potatoes generously with salt and pepper to taste. Continue mashing until you reach your desired consistency, adding a splash more milk if you prefer them looser. Be careful not to overmix, as this can make the potatoes gummy.

Frequently Asked Questions:
Can I use a different cut of beef for the Steak Bites & Mash?
Absolutely! While sirloin or ribeye are excellent choices for their tenderness and flavor, you can certainly use other cuts like filet mignon for an even more luxurious dish, or flank steak if you prefer a slightly chewier texture (just be sure to slice it against the grain). The key is to choose a cut that is relatively tender and sears well.
What can I serve with Steak Bites & Mash besides the suggested sides?
The versatility of Steak Bites & Mash means it pairs well with a wide array of sides. Consider roasted Brussels sprouts, glazed carrots, a corn and avocado salsa, or even a flavorful mushroom risotto for a more elevated meal. A crusty bread to soak up any extra sauce is also a wonderful addition.
How can I make the mashed potatoes even creamier?
To achieve exceptionally creamy mashed potatoes for your Steak Bites & Mash, use starchy potatoes like Russets or Yukon Golds. Warm your dairy (milk, cream, or half-and-half) before adding it to the mashed potatoes, and consider adding a generous knob of butter or a dollop of sour cream or cream cheese for extra richness and smoothness.
