Ingredients
  

Steak Bites
  • 2 lbs steak (filet, ribeye, or sirloin) cut into 2‑3‑inch pieces
  • avocado oil for rubbing the steak
  • blackened cajun seasoning for coating
Parmesan Cream Sauce
  • 5 tbsp butter divided
  • 10 cloves garlic, minced divided
  • 1.5 cups heavy cream
  • 2 green onions, diced (green and white parts)
  • 1 tsp red pepper flakes
  • 2/3 cup parmesan cheese, grated
Cheesy Mashed Potatoes
  • 4 lbs russet potatoes
  • 1 cup half and half warmed
  • 6 tbsp salted butter melted
  • 3/4 cup Monterey Jack or mozzarella cheese shredded
  • 1 tsp garlic powder
  • 3/4 tsp salt
  • black pepper to taste

Equipment

  • Cast Iron Skillet

Method
 

  1. Cut the steak into 2‑3‑inch pieces. Rub with avocado oil and coat evenly with blackened cajun seasoning. Let sit for 10–15 minutes at room temperature.
  2. Peel and quarter the potatoes. Soak in cold water for 10 minutes to remove excess starch, then boil in salted water until fork‑tender.
  3. In a hot cast‑iron skillet over medium‑high heat, sear the steak bites in batches (don’t overcrowd) for about 2 min on each side until golden. Remove and keep warm.
  4. In the same skillet, add 3 tbsp butter and 1 tbsp minced garlic; sauté until fragrant, then toss steak bites to coat. Remove and tent with foil.
  5. For the sauce: add remaining 2 tbsp butter and remaining garlic to the skillet, sauté until fragrant. Whisk in heavy cream, simmer for 3–5 min until reduced. Stir in red pepper flakes, green onions, and parmesan until thickened. Season to taste.
  6. Meanwhile, drain potatoes and mash with warmed half‑and‑half, melted butter, shredded cheese, garlic powder, salt, and pepper until smooth.
  7. Serve steak bites over the cheesy mashed potatoes and spoon the parmesan cream sauce over the top.

Notes

A cozy, comforting dish perfect for sharing. You can lighten it using evaporated milk instead of cream or mashed cauliflower for the potatoes.
