Baked Barbeque Beans

I've had this recipe for about 15 years...and it's still my favorite one for baked beans.

1 53 oz can pork 'n beans (do not drain)
1 cup ketchup
1 cup brown sugar (I use less)
2 Tbsp. worchestershire sauce
1 tsp liquid smoke
2 Tbsp. minced onion (you can use the dehydrated kind)
3-6 slices raw bacon (I prefer to use 1 package of Hormel REAL bacon bits)

Mix the above ingredients. Pour into baking dish (9x13). Bake uncovered for 2 hours at 325, but cover if the beans start to dry out.
