Good old fashioned baked beans

I made these in the slow cooker yesterday and they are wonderful. When I was a kid growing up, my Mom used to make great baked beans like this all the time. They are really inexpensive to make and you can't get a taste like them from a can.

Kathi’s Old Fashioned Baked Beans (can also be made in the slow cooker)

1 pound dried navy or great northern beans
2 tablespoons olive oil
1 cup chopped onions
2 cloves garlic, chopped
1 ½ cups dark brown sugar
2 cups ketchup
6 tablespoons maple syrup
6 tablespoons dark molasses
½ cup soy sauce -make sure it is gf!
½ teaspoon salt
¼ teaspoon pepper

Rinse and pick through the beans. Soak them overnight in a large pot of water.
Rinse the soaked beans well under cold water, and place them in a heavy saucepan. Cover with water and bring to a boil. Reduce the heat and simmer covered until tender – an hour or two. Drain.
Heat the olive oil in a large heavy saucepan. Add the onions and garlic and cook until wilted – about 5 minutes.
Add the brown sugar and stir over medium-low heat until it has dissolved, about 5 minutes. Stir in ketchup, syrup, molasses, soy sauce, salt and pepper. Mix well.
Pour Beans into an oven proof 2 quart casserole dish. Pour sauce over them and mix well.
Cover the casserole and cook in oven at 300 degrees, stirring occasionally for 3 hours.
Uncover, stir and bake uncovered until the sauce is thick and syrupy.
