Best Maccaroni every

On Saturday I had the privilege of participating in a birthday party. I wanted to bring something so I made my most popular Macaroni and cheese. Everything was from Aldi. I was wonderful. I had the chance to make a big batch and I put it in my crock pot and baked it for four hours. Here is the recipe:

1 8 oz box of elbow macaroni cooked according to direction
8 oz sour cream
8 oz mayonnaise
4 cups shredded cheddar cheese
1 Tbs dried onion flakes or 1/4 cup chopped onion
salt and pepper to taste
crushed saltine crackers

Cook macaroni, rinse and drain. Mix together rest of ingredients except crushed crackers. Mix in macaroni and put in a large buttered baking dish. Top with crushed crackers and bake 350 degrees for 30 - 45 minutes. SOOOO GOOD!
