Ingredients
Oops! Something went wrong. Our team is working on it.
2 ½ pounds thick-cut, bone-in ribeye steak
¾ teaspoon kosher salt, divided
¾ 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
¾ cup shredded white Cheddar cheese
½ cup shredded mozzarella cheese
¼ cup shredded Parmesan cheese
Directions
Sprinkle steak with 1/2 teaspoon salt and 1/2 teaspoon pepper.
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.
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.
Preheat the oven to 425 degrees F (220 degrees C). Arrange bread on a small baking sheet.
Bake bread in the preheated oven until toasted, about 6 minutes.
Stir mozzarella cheese and Parmesan cheese together in a small bowl.
Remove and discard bones and thyme sprigs from the pot. Skim off any excess fat. Stir in remaining salt and pepper.
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.
Broil soups until cheese is browned and bubbly, 1 to 2 minutes. Watch closely to prevent burning.
Cook's Note:
You can use lemon thyme if preferred.
