Notes from our test kitchen; make certain not to cook the sweet potatoes until mushy soft cook only until fork tender they may be cooked up to a few days ahead and refrigerated until ready to use, the amounts may be doubled if desired to serve 8
Servings 4
Ingredients:
4 medium cooked sweet potatoes, peeled and sliced about 1/2-inch thick or a little smaller
1/4 cup butter (can use the bacon fat mixed with butter to make about 1/4 cup)
1 small onion, finely chopped
3 garlic cloves, minced
1 (10-ounce) package chopped frozen spinach, thawed (hand-squeeze out all excess moisture)
1/4 cup all-purpose flour
1/2 teaspoon salt, or to taste (I use seasoned salt)
1/4 teaspoon ground nutmeg
fresh ground black pepper, to taste
pinch cayenne pepper, optional
1/2 cup heavy whipping cream (33-35%)
1-1/2 cups cups light cream (can use milk)
1/4 to 1/3 cup freshly grated Parmesan cheese
2 cups shredded mozzarella cheese or Gouda cheese (I prefer the Gouda)
3 bacon slices, cooked and crumbled
Instructions:—————————————
Preheat oven to 375 degrees F.
Set oven rack to lowest position.
Generously grease an 11 x 7-inch baking dish or use a similar size casserole dish.
In a skillet melt butter over medium-high heat.
Add in onion and saute until tender (about 3-4 minutes).
Add in garlic and spinach; cook stirring for 3 minutes.
Stir in the flour with next 4 seasonings; stir with wooden spoon for 1 minute.
Slowly add in whipping cream and light cream stirring constantly until thickened, then mix in the Parmesan cheese; remove from heat and set aside.
To assemble;
Spread half of the spinach mixture into the bottom of the baking dish, then top with half of the sliced sweet potatoes then half of the shredded mozzarella cheese.
Repeat with remaining half the spinach mixture, sweet potato slices then the remaining shredded mozzarella cheese on top.
Sprinkle the crumbled bacon over the top of the casserole.
Cover with foil and bake for 12-15 minutes or until just heated through (if you are using cold sweet potatoes from the fridge cooking time may take longer).
