Ingredients
  

For the Steak:

  • 2 lbs steak filet ribeye, or sirloin
  • 4 –5 tablespoons avocado oil

For the Parmesan Cream Sauce:

  • 5 tablespoons butter divided
  • 10 cloves garlic minced (divided use)
  • 1.5 cups heavy cream
  • 2 green onions diced (green and white parts)
  • 1 teaspoon red pepper flakes adjust to taste
  • 2/3 cup grated parmesan cheese

For the Cheesy Mashed Potatoes:

  • 4 lbs russet potatoes peeled and quartered
  • 1 cup half and half warmed
  • 6 tablespoons salted butter melted
  • 3/4 cup shredded Monterey Jack cheese or mozzarella, pepper jack, etc.
  • 1 teaspoon garlic powder
  • 3/4 teaspoon salt
  • 1/2 teaspoon black pepper or to taste

For the Homemade Blackened Seasoning:

  • 2 tablespoons smoked paprika
  • 1 tablespoon cayenne pepper
  • 1 tablespoon onion powder
  • 2 teaspoons garlic powder
  • 1 teaspoon ground black pepper
  • 1 teaspoon salt
  • 1/2 teaspoon dried thyme
  • 1/2 teaspoon dried oregano

Instructions
 

Prepare the Ingredients:

  • Cut steak into 2 to 3-inch pieces. Rub with avocado oil and generously coat with the blackened seasoning mix. Let sit at room temperature for 10–15 minutes.
  • Place peeled, quartered potatoes in a bowl of cold water for 10 minutes to remove excess starch. Drain, then boil in salted water until fork tender.

Sear the Steak:

  • Heat 2–3 tablespoons of avocado oil in a large skillet over medium-high heat. Sear the steak pieces undisturbed for about 2 minutes until golden. Flip once, cook for another minute, then lower the heat and cook for 1 more minute.
  • Remove the steak from the pan and set aside. In the same pan, melt 3 tablespoons of butter with 1 tablespoon of garlic. Sauté until fragrant. Toss the steak in the garlic butter and cook for an additional minute. Remove and keep warm under foil.

Make the Parmesan Cream Sauce:

  • Using the same pan, add the remaining 2 tablespoons of butter and minced garlic. Cook until fragrant.
  • Slowly whisk in the heavy cream and bring to a simmer. Let reduce for 3–5 minutes.
  • Stir in red pepper flakes, diced green onions, and parmesan cheese. Whisk until smooth and thickened. Season to taste.

Prepare the Cheesy Mashed Potatoes:

  • Drain the cooked potatoes. Add the melted butter and warm half and half. Mash until smooth.
  • Stir in shredded cheese, garlic powder, salt, and pepper. Mix until creamy and fully combined.

Assemble and Serve:

  • Plate the mashed potatoes, top with blackened steak, and drizzle generously with the parmesan cream sauce.
