There’s something magical about the combination of perfectly seared steak bites swimming in rich garlic butter, paired with creamy, fluffy mashed potatoes. I’ve been perfecting this recipe for years, and it never fails to impress whether I’m cooking for my family on a weeknight or entertaining guests on the weekend.
The beauty of garlic butter steak bites lies in their simplicity and speed. Unlike cooking a whole steak, these bite-sized pieces cook in minutes while developing a beautiful caramelized crust. When combined with aromatic garlic butter and served alongside perfectly smooth mashed potatoes, you get a restaurant-quality meal that’s surprisingly easy to make at home.
What Makes This Recipe Special
I’ve tried countless variations of steak bites over the years, but this particular combination hits all the right notes. The key is in the technique – getting your pan screaming hot before adding the steak, using the right cut of meat, and timing everything perfectly so the garlic doesn’t burn while the butter creates that glossy, aromatic coating.
The mashed potatoes aren’t just a side dish here; they’re the perfect vehicle for soaking up all that delicious garlic butter. I use a combination of techniques to ensure they’re impossibly creamy without being gluey – a common mistake that can ruin an otherwise perfect meal.
Choosing the Right Cut of Steak
Sirloin: My go-to choice for steak bites. It’s tender, flavorful, and won’t break the bank. The marbling is just right for quick cooking.
Ribeye: If you want to splurge, ribeye creates incredibly tender, juicy bites with rich flavor from the fat content.
Strip Steak: Another excellent option that’s tender and has good beefy flavor without being too expensive.
Tenderloin: The most tender option, but also the most expensive. Perfect for special occasions.
Avoid: Tough cuts like chuck or round steak, which need long, slow cooking to become tender.
| Cut | Tenderness | Flavor | Price Point | Best For |
|---|---|---|---|---|
| Sirloin | Good | Excellent | Budget-friendly | Everyday meals |
| Ribeye | Excellent | Rich | Expensive | Special occasions |
| Strip Steak | Very Good | Good | Moderate | Weekend dinners |
| Tenderloin | Outstanding | Mild | Very Expensive | Celebrations |
Essential Ingredients and Their Roles
For the Steak Bites:
- 2 lbs sirloin steak, cut into 1-inch cubes – The star of the show
- 3 tablespoons olive oil – For high-heat searing
- 4 tablespoons butter – Creates the rich base for our garlic butter
- 6 cloves garlic, minced – Aromatic foundation
- 2 tablespoons fresh thyme – Earthy herb that complements beef perfectly
- 1 tablespoon fresh rosemary, chopped – Adds pine-like fragrance
- Salt and black pepper – Essential seasoning
- 1 tablespoon Worcestershire sauce – Adds umami depth
For the Mashed Potatoes:
- 3 lbs Yukon Gold potatoes – Best variety for creamy texture
- 8 tablespoons butter – For richness
- 1/2 cup heavy cream – Creates silky smoothness
- 1/4 cup sour cream – Adds tang and extra creaminess
- Salt and white pepper to taste – Seasoning without black specks
- 2 tablespoons chives, chopped – Fresh garnish
The Science Behind Perfect Steak Bites
Understanding the Maillard reaction is crucial for perfect steak bites. This chemical reaction between amino acids and sugars occurs at high temperatures (around 300°F and above) and creates those complex, savory flavors and beautiful brown crust we’re after.
The key is getting your pan hot enough before adding the steak. I use a cast iron skillet because it retains heat well and creates excellent searing. When the oil shimmers and just begins to smoke, that’s your cue to add the steak cubes.
Don’t overcrowd the pan – this is perhaps the most common mistake I see. When too many pieces are added at once, they steam instead of sear, resulting in gray, tough meat instead of the golden-brown, tender bites we want.
Step-by-Step Cooking Instructions
Preparing the Potatoes (Start Here – 45 minutes total)
- Prep the potatoes: Peel and cut Yukon Gold potatoes into evenly sized chunks, about 2 inches. This ensures even cooking.
- Cold water start: Place potato chunks in a large pot and cover with cold, salted water by about 2 inches. Starting with cold water helps them cook evenly.
- Boil until tender: Bring to a boil over high heat, then reduce to a steady simmer. Cook for 15-20 minutes until a fork easily pierces the largest piece.
- Drain thoroughly: Drain in a colander and let sit for 2-3 minutes to allow excess moisture to evaporate. This prevents watery mashed potatoes.
- Mash while hot: Return to the pot and mash with a potato masher or ricer while still hot. Hot potatoes absorb butter and cream better.
- Add dairy gradually: Warm the cream and butter together, then add gradually while mashing. This prevents lumps and creates silky texture.
- Season and finish: Add sour cream, salt, and white pepper. Taste and adjust seasoning. Keep warm while preparing steak bites.
Preparing the Steak Bites (15 minutes)
- Prep the steak: Remove steak from refrigerator 20 minutes before cooking to bring to room temperature. Cut into uniform 1-inch cubes against the grain.
- Season generously: Pat steak cubes dry with paper towels, then season all sides with salt and pepper at least 10 minutes before cooking.
- Heat the pan: Preheat a large cast iron skillet over medium-high heat until smoking. Add olive oil and swirl to coat.
- Sear the steak: Add steak cubes in a single layer, leaving space between pieces. Don’t move them for 2-3 minutes to develop a crust.
- Flip and sear: Using tongs, flip each piece and sear the other sides for another 1-2 minutes total. The internal temperature should reach 130°F for medium-rare.
- Create garlic butter: Reduce heat to medium-low. Add butter to the pan and let it melt. Add minced garlic, thyme, and rosemary.
- Baste and finish: Swirl the pan to combine the garlic butter, then spoon it over the steak bites. Add Worcestershire sauce and toss to coat.

| Well-Done | 155°F+ | 5+ minutes | No pink |
Pro Tips for Success
Steak Preparation Tips:
- Room temperature is key: Cold steak won’t sear properly and may cook unevenly
- Pat dry thoroughly: Moisture is the enemy of good searing
- Don’t move too soon: Let that crust develop before flipping
- Use tongs, not a fork: Piercing releases juices
- Rest after cooking: Even steak bites benefit from a brief rest
Mashed Potato Perfection:
- Choose the right potato: Yukon Gold has the perfect starch content
- Don’t overmix: This develops gluten and creates gluey texture
- Warm your dairy: Cold cream and butter can make potatoes dense
- Season in layers: Salt the cooking water and season the finished potatoes
- Serve immediately: Mashed potatoes are best served hot and fresh
Flavor Variations and Customizations
Herb Variations:
- Mediterranean: Add oregano, basil, and sun-dried tomatoes
- French: Use tarragon, parsley, and a splash of cognac
- Asian-inspired: Ginger, sesame oil, and green onions
- Southwestern: Cumin, chili powder, and lime zest
Potato Variations:
- Loaded: Add bacon bits, cheddar cheese, and green onions

Troubleshooting Common Issues
Problem: Steak bites are tough
Solution: You likely overcooked them or used a tough cut. Next time, use a tender cut and cook for less time.
Problem: Garlic is burnt and bitter
Solution: Add garlic after reducing heat and don’t let it cook too long. Burnt garlic ruins the whole dish.
Problem: Mashed potatoes are gluey
Solution: You overmixed them. Use a potato masher or ricer, and fold in dairy gently.
Problem: Mashed potatoes are watery
Solution: Drain potatoes thoroughly and let them sit for a few minutes before mashing. Also, warm your dairy before adding.
Problem: Steak bites are gray instead of brown
Solution: Your pan wasn’t hot enough, or you overcrowded it. Use higher heat and cook in batches if necessary.
Questions and Answers
Q: Can I use frozen steak for this recipe? A: While fresh is always better, you can use frozen steak if you thaw it completely first. Pat it extra dry and let it come to room temperature before cooking.
Q: What’s the best way to cut steak into cubes? A: Cut against the grain in 1-inch strips first, then cut those strips into 1-inch cubes. This ensures maximum tenderness.
Q: Can I make the mashed potatoes ahead of time? A: Yes, you can make them up to 2 days ahead. Store in the refrigerator and reheat gently with a splash of cream or milk.
Q: How do I know when my pan is hot enough? A: The oil should shimmer and move freely around the pan. You can also test by dropping a small piece of steak – it should sizzle immediately.
Q: Can I use a different type of potato? A: Yukon Gold is ideal, but Russets work too. Avoid waxy potatoes like red potatoes as they don’t mash well.
Q: What if I don’t have fresh herbs? A: You can substitute with dried herbs, but use about 1/3 the amount. Fresh herbs provide much better flavor, though.
Q: Can I make this recipe with chicken instead? A: Absolutely! Chicken thighs work particularly well. Just adjust cooking time to ensure they reach 165°F internal temperature.
Q: How do I prevent the butter from burning? A: Keep the heat at medium-low once you add the butter, and don’t let it sit too long. The residual heat from the pan and steak will be enough.
Q: Can I double this recipe for a crowd? A: Yes, but cook the steak bites in batches to avoid overcrowding. You can double the mashed potato recipe easily.
Q: What’s the best way to season the steak? A: Salt and pepper at least 10 minutes before cooking allows the seasoning to penetrate. For best results, season 40 minutes to 1 hour ahead.
