found recipe on Moms with crock pots8 oz medium shell macaroni
2 tsp olive oil
1 cup evaporated milk
1/2 cup milk
1/2 tsp salt
1/4 tsp pepper
2 cups (8 oz) shredded sharp cheddar cheese or a Cheddar blend
4 Tbsp butter, melted
Cook macaroni following package directions.
drain and rinse with hot water, drain well
Generously butter the sides and bottom of a 3 1/2 to 4 quart slow cooker
( I used about 2 Tbsp of butter)
Combine macaroni with remaining ingredients in the slow cooker and blend well.
Cover and cook on low for 2 1/2 to 3 1/2 hours, stirring occasionally
If desired, when macaroni and cheese is done, spoon mixture into baking dish, sprinkle with a little more cheese or bread crumbs, and put under the broiler for a 1-2 minutes, getting the "fresh from the oven" look
Side note: When we made it, it looked great after 2 hours, but at 3 hours it was starting to get a little lumpy. It still tasted great, and we plan on making it again, but will plan on only 2 to 2 1/2 hours in the crock pot.
