Tortellini Spinach Bake w Creamy Lemon Sauce

This was amazing!  Every bite I kept saying mmmm, we loved it!  I later made it for a friend who just had a baby and also for my bible study group's freezer meal swap (it froze and reheated well I think!).  The lemon was such a bright surprise.  I added mushrooms in ours as well, but you can definitely leave that out if you wish.

Tortellini Spinach Bake in Creamy Lemon Sauce
via Our Best Bites

12 oz bag Cheese Tortellini (I used frozen)
4 strips bacon, diced
3 cloves garlic, finely minced
2 Tbs flour
2 C milk
¾ tsp kosher salt
⅛ tsp black pepper
1 1/2 tsp dry basil
¼ tsp red pepper flakes (1/2 tsp or more if you like spicy)
1 medium lemon
2 C loosely packed fresh spinach, roughly chopped (I used 8 oz frozen, dethawed and squeezed water out)
1/2 cup sliced mushrooms
¾ C grated mozzarella cheese, divided
¾ C grated Parmesan cheese, divided

Preheat oven to 350 degrees.  Fill a large stock pot with water and bring to a boil.  Add tortellini and cook according to package instructions.

Place bacon and mushrooms in a medium sized skillet on the stove-top at medium-high heat.  Cook until bacon is crisp.  Remove bacon from pan with slotted spoon and set on paper towels to drain.  Reserve two tablespoons bacon drippings in pan and discard the rest.  Add garlic to pan and cook until fragrant and tender, about 1 minute.  Add flour to pan and stir with a whisk for about 1 minute. Slowly add milk and continue to stir with whisk until smooth.  Add salt, pepper, basil, and red pepper flakes and bring sauce to a simmer.

While sauce is heating, use a microplane grater or a fine-holed cheese grater to zest lemon.  Then cut lemon in half and remove juice.  Add 2 teaspoons zest and 1 tablespoon lemon juice to sauce.  (Note:  I really love lemon so I added this to my tastes.  If you don’t want as strong of a lemon flavor, I suggest cutting it down to 1 teaspoon zest and 2 teaspoons lemon juice) .  Continue to stir until thickened, 2-3 minutes.  Remove from heat.

Drain tortellini and place back in stock pot.  Reserve 1 tablespoon of the cooked bacon and add the rest to the pasta mixture.  Add spinach, 1/2 cup mozzarella cheese and 1/2 cup Parmesan cheese.  Add sauce and gently stir to combine.  Place pasta mixture in an 8×8 or 9×9 baking dish and top with remaining 1/4 cup mozzarella and 1/4 cup parmesan and also crumbled bacon.

Cover pan with foil and bake for 20 minutes.  Remove foil and bake for an additional 5-10 minutes, until cheese on top is melted and pasta is bubbly throughout.  Remove from oven and serve!
