Ingredients

• 2 pieces grass-fed steak (ribeye, sirloin, or NY strip)
• 2 tablespoons avocado oil
• 1 teaspoon kosher salt
• 1 teaspoon black pepper
• 2 cups white or cremini mushrooms, sliced
• 1 large yellow onion, thinly sliced
• 2 cloves garlic, minced
• 1 teaspoon fresh thyme leaves
• 1 tablespoon balsamic vinegar (Whole30-compliant, no added sugar)
• 2 tablespoons ghee

Directions

Step 1

Remove the steaks from the fridge and let them come to room temperature for about 20 minutes.

Step 2

Season the steaks on both sides with the kosher salt and black pepper.

Step 3

Heat 1 tablespoon of avocado oil in a large skillet over medium-high heat. Once the oil is hot and shimmering, add the steaks.

Step 4

Cook the steaks for about 3-4 minutes per side for medium-rare, or longer if you prefer a different doneness. Use a meat thermometer if needed (135°F for medium-rare).

Step 5

Remove the steaks from the skillet and set them aside to rest, loosely covered with foil.

Step 6

In the same skillet, add the remaining 1 tablespoon of avocado oil and reduce the heat to medium.

Step 7

Add the sliced onion and sauté for 5-7 minutes, stirring occasionally, until softened and starting to caramelize.

Step 8

Add the sliced mushrooms to the onions and cook for an additional 5 minutes, stirring occasionally, until the mushrooms are tender and golden brown.

Step 9

Add the minced garlic and fresh thyme leaves. Sauté for 1-2 minutes until fragrant.

Step 10

Deglaze the skillet by adding the balsamic vinegar, stirring to scrape up any browned bits from the bottom of the pan. Let it cook for 1-2 minutes to reduce slightly.

Step 11

Stir in the ghee and let it melt into the mushroom and onion mixture for added richness.

Step 12

Place the steaks back into the skillet or serve them on plates with the sautéed mushrooms and onions spooned over the top.

Step 13

Serve immediately and enjoy your delicious Whole30-compliant steak dinner!
