Swaps and Notes
- Steak: Swap sirloin for ribeye, NY strip, or even tenderloin
- Herbs: Fresh thyme or rosemary work beautifully, too
- Potatoes: Russet potatoes also mash well—just add more cream
- Green beans: Try asparagus or broccolini for a twist
- Add spice: Toss red pepper flakes into the garlic butter for a kick
Step-by-Step Instructions
🔹 Step 1: Prepare the Mashed Potatoes
Bring a large pot of salted water to a boil.
Add cubed potatoes and boil for 15–20 minutes, until fork-tender.
Drain and return to the pot. Mash with:
- Heavy cream
- Milk
- Parmesan cheese
- Salt and pepper to taste
Set aside, covered, to keep warm.
🔹 Step 2: Cook the Green Beans
In a skillet, bring ½ inch of water to a simmer.
Add green beans and steam, covered, for 5–7 minutes until tender-crisp.
Drain and toss with:
- 1 tablespoon butter
- 1 tablespoon lemon juice
- Salt and pepper
Transfer to a serving dish and keep warm.
🔹 Step 3: Sear the Steak Bites
Pat steak cubes dry and season with:
- Salt
- Pepper
- Dried thyme
- Dried rosemary
Heat a large skillet over medium-high heat. Add:
- 1 tablespoon olive oil
- 2 tablespoons butter
When hot, add steak in a single layer. Sear for 2–3 minutes per side until browned. Remove and set aside.
🔹 Step 4: Make the Garlic Butter Sauce
In the same skillet, melt the remaining 1 tablespoon butter.
Add minced garlic and sauté for 30 seconds until fragrant.
Return the steak to the pan and toss to coat in the garlic butter.
🔹 Step 5: Plate and Serve
Spoon mashed potatoes onto plates, top with steak bites and drizzle garlic butter sauce over top.
Add a serving of green beans on the side and garnish with chopped parsley.
Tips for Success
- Use a hot skillet: A proper sear = big flavor
- Dry your steak: Patting the beef dry before seasoning helps browning
- Don’t crowd the pan: Sear steak in batches if needed
- Creamy mash tip: Warm the cream/milk before mashing for better texture
- Brighten your beans: Lemon juice brings the whole plate to life
Serving Suggestions and Pairings
Round out this hearty dinner with:
- A crusty bread roll or warm biscuit
- Dorito Casserole – for a full-on comfort feast
- Easy Turkey Wings – mix and match your mains
- One-Pan Breakfast Bake – perfect for the next day’s brunch
- Blueberry Lemonade – cuts the richness beautifully
- Chocolate Chip Cookie Dough Brownie Bombs – an indulgent way to end the meal
Storage and Leftovers
- Fridge: Store steak, potatoes, and green beans in separate containers for up to 3 days
- Reheat: Warm steak gently in a skillet or microwave in short bursts
- Freezer: The mashed potatoes and steak freeze well (green beans less so)
