Make-Ahead and Storage Tips

The mashed potatoes can be made ahead and reheated with a splash of milk. Store beef bites and potatoes separately in airtight containers for up to 3 days. Reheat gently to keep the beef tender. This dish doesn’t freeze well due to the texture of the potatoes, but the beef on its own can be frozen.

How to Serve Garlic Butter Beef Bites with Creamy Mashed Potatoes

Plate the mashed potatoes in a big swoop, letting the garlic butter from the beef drizzle down like a sauce. Serve with roasted green beans, sautéed spinach, or a crisp side salad for balance. For a special touch, sprinkle flaky salt and a few fresh parsley leaves over the top.

Creative Leftover Transformations

Turn your extras into magic.

• Make a beef and mashed potato bowl with gravy and veggies.
• Use beef bites in a wrap with arugula and creamy sauce.
• Form leftover mash into patties and pan-fry until crispy.
• Add the beef to scrambled eggs for a protein-packed breakfast.

Additional Tips

• Want extra garlicky goodness? Roast garlic cloves and mash into the potatoes.
• Add horseradish or Dijon to the mash for a flavorful twist.
• Don’t skip the garnish — parsley or chives add color and freshness.

Make It a Showstopper

Sear the beef until each bite has a golden crust, and spoon over that glossy garlic butter right before serving. Use a ring mold to shape the mashed potatoes for a restaurant-style plate. Garnish with cracked black pepper, paprika, and chopped herbs.
