2 large onions, finely chopped (about 3 cups chopped onions)
2 T olive oil
1 T butter
large pinch salt
1 cup sour cream
½ c. mayonnaise
1 small pinch cayenne pepper
salt to taste
Instructions
Place onions, oil, butter and pinch of salt into a slow cooker, and stir to coat. Cook on high for 8 hours, or until onions are deep caramel brown.
Drain any liquid off the onions. Combine half the onions with remaining ingredients in a small bowl, salt to taste. Serve with potato chips and enjoy the Superbowl.
Notes
My slow cooker works best if I cook larger amounts, so I make a lot of onions and use only half for the dip. The rest can go in the refrigerator and be used in pizzas, sandwiches, or to make an instant french onion soup.
