Boil the Potatoes: Place chopped potatoes in a pot of salted water. Bring to a boil and cook until tender, about 15–20 minutes.
Mash: Drain the potatoes and return them to the pot. Add butter, milk, and optional sour cream. Mash until smooth and creamy. Season with salt and pepper to taste.
Cook the Beef Bites:
Heat Oil and Butter: In a large skillet, heat olive oil over medium-high heat. Add butter and let it melt.
Sauté Garlic: Add minced garlic and sauté for 30 seconds until fragrant.
Cook Beef: Add beef bites to the skillet. Season with salt, pepper, and optional herbs. Cook for 3–5 minutes, stirring occasionally, until browned and cooked to your desired doneness.
Serve:
Spoon a generous portion of mashed potatoes onto each plate.
Top with garlic butter beef bites.
Drizzle any pan juices over the dish for extra flavor.
