Mashed Potatoes
Cook the Potatoes: In a large pot, add the potato chunks and cover with cold water. Bring to a boil over high heat and cook until the potatoes are tender, about 15-20 minutes.
Mash the Potatoes: Drain the potatoes and return them to the pot. Add the milk, butter, sour cream, sea salt, and black pepper. Mash until smooth and creamy. Keep warm.
Green Beans
Cook the Green Beans: In a large skillet, heat olive oil over medium-high heat. Add the trimmed green beans and cook, stirring occasionally, until they are tender and slightly charred, about 5-7 minutes.
Add Garlic and Seasoning: Add the minced garlic, sea salt, black pepper, and red pepper flakes (if using). Cook for another 1-2 minutes until the garlic is fragrant. Remove from heat and keep warm.
Steak Bites
Cook the Steak: In a large skillet, heat olive oil over high heat. Add the steak cubes in a single layer, making sure not to overcrowd the pan.
Cook for 2-3 minutes on each side until browned and cooked to your desired doneness. Remove the steak from the skillet and set aside.
Make the Garlic Butter: In the same skillet, reduce the heat to medium. Add the unsalted butter and minced garlic. Cook until the butter is melted and the garlic is fragrant, about 1-2 minutes. Stir in the dried thyme, dried rosemary, sea salt, and black pepper.
Combine Steak and Garlic Butter: Return the steak bites to the skillet and toss to coat in the garlic butter. Cook for an additional 1-2 minutes until the steak is warmed through.
Serve
Assemble the Plate: Divide the mashed potatoes among plates. Top with garlic butter steak bites and a side of green beans.
Garnish: Garnish with chopped fresh parsley and serve immediately.
