This is a special occasion favorite of ours. I'm sure your family will love it as well. It really does need the onion to give it flavor, so put it in even if you aren't a fan of onions.
Hot Bacon Cheese Spread ~
1 loaf (16 ounces) round bread, unsliced
1/2 pound of bacon, cook till crisp and crumble
8 oz. shredded Colby/Monterey Jack Cheese
4 to 6 ounces grated parmesan cheese
1 cup mayonnaise
1/4 cup onion, finely chopped
1 or 2 cloves garlic minced.
Cut a lengthwise slice from the top of the bread loaf. Take out the center and leave a 1 inch thick shell. cut the unused bread into bite size chunks to use as dippers.
Mix everything else in a bowl and spoon into the bread shell. Put the top back on the bread and place on a cookie sheet.
Bake at 350' for 1 hour. Serve with bread or crackers (I like Wheat thins with this).
If there is any left, you can cover it and put in the fridge. It reheats real well in a microwave.
