Ingredients
Main Ingredients
- 6 tablespoons Butter for caramelizing onions
- 4 Large yellow onions sliced into rings
- 1 tablespoon White sugar for caramelization
- 2 cloves Garlic minced
- 0.5 cup Cooking sherry
- 7 cups Reduced-sodium beef broth
- 1 teaspoon Sea salt
- 0.25 teaspoon Dried thyme
- 1 Bay leaf
- 8 slices French bread for topping
- 0.5 cup Shredded Gruyere
- 0.33 cup Shredded Emmental
- 0.25 cup Parmesan
- 2 tablespoons Mozzarella
Instructions
Instructions
- Melt butter in a large skillet over medium heat so it’s nice and hot but not burning.
- Add those sliced onions and stir often till they turn soft and start caramelizing, about 20 to 25 minutes.
- About 5 minutes before done, sprinkle sugar and garlic in to help with that sweet tender pull.
- Transfer caramelized onions to your pressure cooker insert. Pour in cooking sherry, beef broth, salt, thyme, and the bay leaf.
- Close the lid and set the valve so the cooker can do its pressure build thing. Cook on high pressure about 10 minutes.
- Once done, go for a slow release so the flavors mellow as the steam escapes. Valve hiss kinda tells you it’s happening.
- Preheat your oven broiler about 15 minutes before serving. Toast your French bread slices till golden on both sides, just 1 to 2 minutes per side.
- Ladle soup into oven-safe bowls, float the toasted bread on top, sprinkle with cheeses, then broil till all melted and bubbly, about 2 to 3 minutes. Serve hot and enjoy!
Notes
Freeze leftovers without the bread and cheese toppings. Reheat and broil fresh for next-day comfort. Caramelizing onions is key!
