Here's another recipe from mom of twins Alyson. Thanks, Alyson!
This recipe takes some time to assemble, but it makes a lot. It reheats well and freezes (uncooked) well. If you freeze it (or freeze half) in an oven-proof dish, you can bake it straight from the freezer.
1 box jumbo pasta shells
3 T. olive oil
1 c. chopped onion
3 cloves garlic, chopped
1 lb. ground chicken
salt and pepper
10 oz pkg. frozen chopped spinach, thawed and squeezed dry
15 oz. container ricotta cheese
3/4 c. grated parmigiano reggiano
2 eggs, lightly beaten
2 T. chopped parsley
1 jar marinara (Rao's and Gia Russo are both delicious)
1 1/2 c. shredded mozzarella
1) Cook the pasta shells in salted water until quite firm, probably about 5 minutes (they will continue to cook when you bake the dish).
2) Meanwhile, saute the onions and garlic in the olive oil over medium-high heat until beginning to brown. Add the chicken, salt and pepper and cook through. Let cool.
3) Combine the cooled chicken mixture, spinach, ricotta, parmigiano reggiano, eggs and parsley.
4) Pour some sauce in the bottom of the dish to coat. Fill the shells with the chicken-cheese mixture and place in the baking dish. Drizzle sauce over shells and sprinkle on the mozzarella cheese.
5) If baking right away, bake at 400 degrees for about 20 minutes until cooked through and slightly browned. If baking from the freezer, bake at 350 degrees for 40 minutes, covered, and 20 minutes, uncovered.
