Ingredients

2 1/2 pounds thick-cut, bone-in ribeye steak
3/4 teaspoon kosher salt, divided
3/4 teaspoon ground black pepper, divided
2 tablespoons unsalted butter
1 tablespoon olive oil
6 large onions, sliced 1/2-inch thick
4 sprigs fresh thyme, or more to taste
2 cups dry white wine
1 (32 ounce) carton reduced-sodium beef broth
4 slices artisanal-style bread
3/4 cup shredded white Cheddar cheese
1/2 cup shredded mozzarella cheese
1/4 cup shredded Parmesan cheese

Directions

1 Sprinkle steak with 1/2 teaspoon salt and 1/2 teaspoon pepper.
2 Heat butter and oil in a 6-quart Dutch oven or heavy-bottomed pot over medium-high heat. Add steak; sear for 2 to 3 minutes per side. Remove steak; drain all but 1 tablespoon drippings. Stir in onions and thyme; cook, stirring occasionally, until onions are tender, about 15 minutes. Add wine and bring to a boil, stirring with a wooden spoon to scrape up any browned bits. Boil until wine is reduced by half, about 15 minutes.
3 Cut steak from the bones and chop into 1-inch pieces; transfer to the pot. Add broth and bring to a boil. Reduce heat; simmer, uncovered, stirring occasionally, until beef is very tender, about 3 hours. Add water as needed to keep onions and beef covered.
4 Preheat the oven to 425 degrees F (220 degrees C). Arrange bread on a small baking sheet.
5 Bake bread in the preheated oven until toasted, about 6 minutes.
6 Stir mozzarella cheese and Parmesan cheese together in a small bowl.
7 Remove and discard bones and thyme sprigs from the pot. Skim off any excess fat. Stir in remaining salt and pepper.
8 Set an oven rack 4 to 6 inches from the heat source and preheat the oven's broiler. Divide soup among 4 oven-proof bowls or mugs; arrange on a large foil-lined baking sheet. Top each bowl with toast and cheeses.
9 Broil soups until cheese is browned and bubbly, 1 to 2 minutes. Watch closely to prevent burning.
