Preheat oven to 220°C (425°F). Scrub and thoroughly pat dry each potato. Rub them with olive oil, then roll in coarse sea salt. Place the seasoned potatoes on a parchment-lined baking sheet and bake for 50-60 minutes, or until completely fork-tender.

While the potatoes bake, trim any excess fat from the steak and cut it into uniform 2.5-5 cm (1-2 inch) cubes. In a mixing bowl, toss the steak cubes with avocado oil and Cajun seasoning until evenly coated.

Heat a cast iron skillet over medium-high heat until hot. Add the seasoned steak bites in a single layer, ensuring not to overcrowd the pan. Sear undisturbed for 2 minutes per side to develop a golden-brown crust. Reduce heat if necessary and continue cooking for approximately 1 additional minute for medium doneness, or to your preferred internal temperature.

Scoot the seared steak bites to one side of the skillet. Add 60 ml (4 tablespoons) of unsalted butter and the minced garlic to the empty side of the pan. Sauté until the garlic is fragrant, about 1 minute. Toss the steak bites in the garlic butter to coat thoroughly. Cook for an additional minute. Remove the steak from the skillet and tent loosely with foil to keep warm.

In the same skillet, add the remaining 30 ml (2 tablespoons) of unsalted butter. Cook for 1 minute over medium heat. Slowly pour in the heavy cream, whisking constantly to ensure smoothness. Simmer, stirring occasionally, until the sauce visibly thickens, approximately 3-5 minutes. Stir in the red pepper flakes (if using) and the grated Parmesan cheese. Whisk until the sauce is smooth and thick. Remove the skillet from heat. Stir in the minced parsley and lemon juice. Taste and adjust seasoning with kosher salt and freshly cracked black pepper as needed.

Carefully drop each baked potato onto a counter from a short height to help loosen the interior flesh. Slice down the center of each potato lengthwise. Fluff the potato flesh with a fork. Spoon generous portions of the garlic butter steak bites into the opened potatoes. Drizzle liberally with the warm Parmesan cream sauce. Garnish with additional fresh parsley or freshly cracked black pepper, if desired. Serve immediately for best enjoyment.
