Ingredients

For the Steak:

2 ribeye steaks (about 1 inch thick)
2 tbsp olive oil

1 tsp salt
1/2 tsp black pepper
1 tsp garlic powder

For the French Onions & Mushrooms:

2 tbsp butter
1 large onion, thinly sliced
8 oz mushrooms, sliced

2 garlic cloves, minced
1 tsp fresh thyme leaves (or 1/2 tsp dried thyme)
1/4 cup beef broth

Salt and pepper, to taste
Fresh parsley, chopped (for garnish)

Preparation

Step 1: Season the Steaks

Start by preparing your ribeye steaks. Rub each steak with 2 tablespoons of olive oil, making sure the oil evenly coats both sides. Then, season each steak with 1 teaspoon of salt, 1/2 teaspoon of black pepper, and 1 teaspoon of garlic powder. Allow the steaks to rest at room temperature for 10-15 minutes. This helps the flavors penetrate the meat and ensures even cooking.

Step 2: Sear the Steaks

Heat a cast-iron skillet or a heavy-bottomed pan over medium-high heat. Once the skillet is hot, add the steaks. Sear the steaks for 3-4 minutes on each side for medium-rare, or adjust the cooking time based on your preferred doneness. For medium, cook the steaks for 4-5 minutes per side. Once cooked, remove the steaks from the skillet and place them on a plate. Cover loosely with aluminum foil to rest while you prepare the onions and mushrooms. Resting allows the juices to redistribute, making the steaks tender and flavorful.

Step 3: Caramelize the Onions

In the same skillet, reduce the heat to medium and melt 2 tablespoons of butter. Add the thinly sliced onions to the skillet and cook, stirring occasionally, for about 10-15 minutes. You want the onions to caramelize and turn a beautiful golden-brown color. The natural sweetness of caramelized onions pairs beautifully with the savory steak.

Step 4: Add the Mushrooms and Garlic

Once the onions are caramelized, add the sliced mushrooms and minced garlic to the skillet. Cook for another 5-7 minutes, stirring occasionally, until the mushrooms are tender and have released their moisture. Add 1 tsp of thyme and stir in 1/4 cup beef broth to deglaze the pan and bring out all the rich flavors. Season with salt and pepper to taste.

Step 5: Serve and Garnish

Generously spoon the caramelized onions and mushrooms over the steaks. Garnish with freshly chopped parsley for a pop of color and a hint of brightness. Serve immediately.

Cooking Notes

Use a cast-iron skillet for the best searing results. Cast iron retains heat evenly and helps develop a rich crust on the steak.
Avoid overcrowding the mushrooms in the pan, as this allows them to cook evenly and release their moisture fully.

Serving Suggestions

Side Dishes: Pair your ribeye steak with creamy mashed potatoes, roasted vegetables, or a fresh green salad for a complete meal. The richness of the steak and mushrooms balances beautifully with light, refreshing side dishes.
Low-Carb Option: For a lower-carb meal, serve the steak with steamed green beans or cauliflower mash instead of potatoes.

Tips for Success

For a more intense garlic flavor, rub a cut garlic clove directly onto the steak before seasoning it with garlic powder.
Let the steak rest for 5-10 minutes before slicing or serving. This ensures the steak retains its juices and remains tender.
Use a thermometer to check the doneness:
Rare: 125°F
Medium-rare: 130°F
Medium: 145°F

FAQs

Q1: Can I use another cut of steak for this recipe?
A: Yes, you can substitute ribeye with other cuts like strip steak or filet mignon. However, ribeye has a higher fat content, which adds to the flavor and tenderness of the dish.

Q2: Can I prepare the onions and mushrooms in advance?
A: Yes, the French onions and mushrooms can be made ahead of time and stored in the refrigerator for up to 3 days. Reheat gently before serving.

Q3: How can I achieve a perfect steak doneness?
A: Using a meat thermometer is the best way to ensure the steak is cooked to your preference. For medium-rare, aim for an internal temperature of 130°F before resting.
