French onion soup

Ingredients

• 3 pounds sweet onions
• 1/4 pound (1 stick) butter
• 2 tbsp olive oil
• 1/2 tsp salt, divided
• 64 oz. good quality beef stock or broth
• 2 sprigs fresh thyme
• 2 bay leaves
• salt and pepper to taste

For Serving

• one loaf crusty french bread
• 4 oz. Gruyere cheese

Directions

Peel, halve and slice the onions. Add butter and oil to an 8-quart pot; add onions in 3 or 4 layers with a sprinkle of salt in between (this will help them reduce more quickly).

Put pot on medium-high (or Normal Saute if using the Instant Pot) and caramelize onions until evenly dark brown and sweet, about 30-45 minutes total, stirring every 5 minutes or so. If using the Instant Pot, cancel Medium Saute after about 15 minutes and switch to Low Saute.

Add beef stock, thyme and bay leaves. Simmer on the stove for as long as you dare, an hour or more. If using the Instant Pot, process on Manual High pressure for 5 minutes, then leave on keep warm all day. Remove thyme springs and bay leaves before serving.

Slice french bread, broil shredded Gruyere cheese on top, and top bowls of soup with the slices.
