Season 1 pound sirloin steak with salt and pepper, and heat 2 tablespoons olive oil in a large skillet over medium-high heat. Slice the steak into strips and sear on all sides until slightly caramelized, about 5 minutes total, and transfer to a plate.
In the same pan, sauté 1 onion, 8 ounces sliced cremini mushrooms, 2 minced garlic cloves and 1 teaspoon minced fresh thyme until the onions are translucent and the garlic is very fragrant, about another 5 minutes.
Pour in 22 ounces L&B Swedish Cream Sauce and ½ cup beef stock, and stir to combine.
Simmer for 15 minutes, then add the steak back to the skillet and simmer for another 3 minutes.
Serve over 1 bag of cooked egg noodles, and garnish with 1 tablespoon fresh parsley.
