Instructions
Prepare the Potatoes
Place the peeled and chopped potatoes in a large pot and cover them with cold, salted water.
Bring to a boil over medium-high heat.
Cook for 15–18 minutes, or until the potatoes are fork-tender.
Drain well and return them to the hot pot for 1–2 minutes to remove excess moisture.
Make the Creamy Mashed Potatoes
Add the butter to the hot potatoes and let it melt.
Pour in the warm heavy cream, sour cream, garlic powder, salt, and black pepper.
Mash until smooth and creamy. For extra silky potatoes, use a potato ricer.
Cover and keep warm while preparing the steak.
Season the Steak
Pat the steak cubes dry with paper towels.
Place them in a large bowl and toss with:
Olive oil
Salt
Black pepper
Garlic powder
Onion powder
Smoked paprika
Italian seasoning
Mix until every piece is evenly coated.
Preheat the Air Fryer
Preheat the air fryer to 400°F (200°C) for 3–5 minutes.
Lightly spray the basket with cooking oil.
Air Fry the Steak
Arrange the steak bites in a single layer in the air fryer basket, leaving space between each piece.
Cook for 4 minutes.
Shake the basket or flip the steak bites.
Cook for another 3–5 minutes, depending on your preferred doneness:
Medium-Rare: 130–135°F (54–57°C)
Medium: 140–145°F (60–63°C)
Medium-Well: 150°F (66°C)
Avoid overcrowding the basket and cook in batches if necessary.
Prepare the Garlic Butter
While the steak cooks, melt the butter in a small saucepan over low heat.
Add the minced garlic and cook for 1 minute until fragrant.
Stir in:
Worcestershire sauce
Fresh parsley
Thyme
Red pepper flakes (optional)
Remove from the heat.
Coat the Steak
Transfer the hot steak bites to a large bowl.
Pour the garlic butter sauce over the steak and gently toss until every piece is coated.
Let the steak rest for 2–3 minutes before serving.
Assemble the Dish
Spoon a generous portion of creamy mashed potatoes onto each serving plate.
Top with the garlic butter steak bites.
Drizzle any remaining garlic butter sauce over the steak and potatoes.
Garnish with chopped parsley, cracked black pepper, and a small pat of butter if desired.
Serve immediately.
Pro Tips
Use sirloin, ribeye, or tenderloin for the most tender steak bites.
Pat the steak dry before seasoning to achieve better browning.
Do not overcrowd the air fryer basket, as this prevents proper air circulation.
Warm the cream before adding it to the potatoes for a smoother texture.
Let the steak rest briefly before serving to keep it juicy.
Fresh garlic and herbs provide the best flavor.
Use a meat thermometer for perfectly cooked steak.
