2 tablespoons high-smoke point oil (avocado or canola oil)

4 cloves of garlic, smashed
3 sprigs of fresh rosemary or thyme
2. For the Loaded Mashed Potatoes
4 large Russet or Yukon Gold potatoes, peeled and cubed
4 tablespoons unsalted butter, softened
1/2 cup sour cream (or heavy cream)
1/2 cup shredded cheddar cheese
1/4 cup cooked bacon bits, chopped
3 green onions (scallions), finely sliced
Salt and black pepper to taste

1 large head of Romaine lettuce, washed, dried, and chopped
1/2 cup store-bought or homemade Caesar dressing

1/4 cup freshly grated Parmesan cheese
Step-by-Step Cooking Instructions
Step 1: Prep the Steak (Crucial for Flavor)
Remove the T-bone steak from the refrigerator at least 30–45 minutes before cooking. Bringing the meat to room temperature ensures even cooking.
Pat the steak completely dry with paper towels. Excess moisture prevents a good sear.
Season generously on all sides (including the edges) with coarse salt and cracked black pepper. Press the seasoning into the meat.
Step 2: Boil and Mash the Potatoes
Place the cubed potatoes into a large pot and cover them with cold water. Add a generous pinch of salt.
Bring to a boil over high heat, then reduce to medium and simmer for 15–20 minutes, or until the potatoes are easily pierced with a fork.
Drain the water completely. Return the potatoes to the hot pot for 1 minute to let any residual moisture evaporate.
Mash the potatoes thoroughly using a potato masher. Mix in the butter and sour cream until perfectly smooth and creamy. Season with salt and pepper.
Top the mashed potatoes with the shredded cheddar cheese, bacon bits, and sliced green onions. Cover with a lid to keep warm and let the cheese melt.
Step 3: Sear the T-Bone Steak
Heat a heavy cast-iron skillet over high heat until it begins to smoke slightly. Add the high-smoke point oil.
Carefully lay the steak in the skillet. Sear the first side without moving it for 2 to 3 minutes until a deep, golden-brown crust forms.
Flip the steak. Immediately lower the heat to medium and add the butter, smashed garlic cloves, and fresh herbs to the pan.
Tilt the skillet slightly and use a large spoon to continuously baste the melted, foamy garlic butter over the top of the steak for another 2 to 3 minutes.
Check the internal temperature using a meat thermometer:
Medium-Rare: 135°F (57°C) — Recommended
Medium: 145°F (63°C)
Remove the steak from the skillet and place it on a cutting board. Let it rest for 5–7 minutes. Resting allows the juices to redistribute back into the meat instead of spilling onto the board.
Step 4: Toss the Caesar Salad
While the steak is resting, place the chopped Romaine lettuce into a large mixing bowl.
Drizzle the Caesar dressing over the lettuce and toss thoroughly until every leaf is lightly coated.
Add the crunchy croutons and grated Parmesan cheese, tossing gently one last time.
Expert Tips for the Ultimate Dinner
Use Cast Iron: A cast-iron skillet retains heat better than any other pan, which is essential for getting that steakhouse-style crust.
Don’t Skip the Rest: Cutting into a steak too early drains the juices and makes the meat tough. Patience results in tenderness!
Dry the Lettuce: Make sure your Romaine lettuce is completely dry after washing, or the Caesar dressing will slide right off and become watery.
