Ingredients
For the Steak Bites
- 1 ½ lbs sirloin steak, cut into bite-sized pieces
- 4 cloves garlic, minced
- 4 tbsp unsalted butter
- 2 tbsp olive oil
- Salt and pepper, to taste
- Fresh parsley, chopped (for garnish)
For the Mashed Potatoes
- 2 lbs russet potatoes, peeled and cut into chunks
- ½ cup whole milk
- 4 tbsp unsalted butter
- ¼ cup sour cream
- Salt and pepper, to taste
Instructions
Step 1: Make the Mashed Potatoes
- Place potato chunks in a large pot and cover with cold water. Add a pinch of salt.
- Bring to a boil and cook for 15–20 minutes, or until fork-tender.
- Drain the potatoes and return them to the pot.
- Add milk, butter, and sour cream. Mash until smooth and creamy.
- Season with salt and pepper to taste. Keep warm.
Step 2: Cook the Steak Bites
- Heat olive oil in a large skillet over medium-high heat.
- Season steak bites with salt and pepper.
- Add steak bites to the skillet in a single layer (work in batches if needed). Cook for 2–3 minutes per side until browned and cooked to your preferred doneness.
- Remove steak bites from the skillet and set aside.
Step 3: Prepare the Garlic Butter Sauce
- In the same skillet, lower the heat to medium.
- Add butter and minced garlic, stirring frequently for 1–2 minutes until fragrant. Be careful not to burn the garlic.
Step 4: Combine and Serve
- Return the steak bites to the skillet and toss to coat in the garlic butter sauce.
- Cook for an additional minute to warm through.
- Spoon the steak bites over a bed of mashed potatoes and drizzle with extra sauce.
- Garnish with chopped parsley and serve immediately.
Serving Suggestions
- Sides: Pair with roasted green beans, sautéed mushrooms, or a fresh garden salad.
- Flavor Twist: Add a pinch of red pepper flakes to the garlic butter for a spicy kick.
- Presentation: Serve in shallow bowls for a rustic, comforting vibe.
Tips for Success
- Steak Doneness: For medium-rare, aim for an internal temperature of 135°F (57°C). Use a meat thermometer for accuracy.
- Potato Texture: For extra creamy potatoes, warm the milk before adding it to the mash.
- Avoid Overcrowding: Cook steak bites in batches to ensure even browning.
- Make Ahead: Prep the mashed potatoes in advance and reheat gently with a splash of milk.
