1 TBS Olive Oil
1/2 stick Butter
1 1/2 cup Mayonnaise
1 block Cream Cheese, softened
1 TBS Dijon Mustard
1 Onion
4 cloves Garlic
1 tsp Pepper
1/2 tsp Salt
10 large basil leaves, minced
1 pkg frozen chopped Spinach, thawed, drained, and squeezed dry
Heat butter and oil in a skillet over medium-low heat. Finely mince onion, I shredded mine with my cheese grater. Mince garlic, I grated mine with a microplane zester. Add onion and garlic to skillet after butter has melted. Allow to cook over low heat until caramel in color, stirring occasionally. This took about an hour.
In the meantime, get out a large bowl, add mayo, cream cheese, Dijon mustard, salt, pepper, and basil. Stir to combine, try to get it nice and smooth. When onions are brown and delicious, add them to the bowl, stir to combine. When all water has been removed from spinach, mix it into the dip. Cover and refrigerate until chilled.
