Cook bacon in medium sauté pan until crispy, then remove and crumble, reserving 1 Tbsp drippings in pan.
Add onions to pan with bacon drippings and sauté until translucent. Add garlic and stir. Remove from heat and toss with bacon crumbles; set aside.
Melt butter in medium saucepan. Whisk in flour; about 1 minute then slowly whisk in cream, until there are no lumps. Simmer until thickened; about 5 minutes.
Stir in salt, pepper and thyme and remove from heat.
Spread 1 layer of sweet potato slices evenly in 9” x 13” pan, overlapping slightly. Season with salt and pepper and spoon 1/3 bacon mixture over potatoes. Pour 1/3 cream mixture on top and sprinkle with 1/3 of cheese.
Repeat steps until potatoes and bacon are gone. Finish with cream mixture and cheese.
Bake 35-45 minutes, or until bubbly. Enjoy.
