1 lb mild or spicy Italian sausage
1 medium onion finely diced
1-2 Tbsp olive oil
16 slices pepperoni
2 24 oz jars basil, garlic, oregano marinara sauce OR your favorite
2 cups low sodium beef stock
2 1/2 cups pasta with ridges (about 2/3 of a 16 oz box) i.e. rigatoni, penne etc.
2 cups shredded mozzarella cheese divided use
1/4 cup grated Parmesan cheese divided use, plus additional for serving
1 tsp garlic salt
1 tsp dry Italian seasoning
1/2 tsp crushed red pepper flakes
1 8 oz ricotta cheese optional
2 Tbsp chopped Italian parsley

Spray the crock of a 6 quart or similar size slow cooker with cooking spray, or line with a crockpot liner.
Sauce: In a skillet, brown sausage and onion in olive oil over medium high heat. Cook just until the sausage has browned it doesn't have to be cooked through. Break sausage into bite size chunks. Drain fat, then arrange on bottom of slow cooker. Cover with pepperoni slices.
To the slow cooker add marinara sauce, broth, garlic salt, Italian seasoning, red pepper flakes and 3 Tbsp Parmesan cheese. Mix the seasonings into the sauce trying not to disturb the sausage. Lock lid in place, simmer on low for 4-6 hours. (Or on high for 2-3 hours)
Pasta: Cook pasta per directions on box in salted water until al dente. Uncover crock pot and add pasta, 1 cup shredded cheese and ricotta, if using.
Cover and cook on high for 15 minutes then top with reserved 1 cup shredded cheese. Let stand with lid offset just until cheese melts.
Garnish with reserved 1 Tbsp Parmesan and fresh parsley and serve.
Please note: At the end of cooking you can thin the sauce by adding additional beef stock or pasta cooking water. Likewise, you can thicken it using tomato paste.

Preheat the oven to 350°F. Spray a 13 x 9 inch baking dish with cooking spray.
Cook the pasta in salted water until al dente, according to the package directions. Drain well, add to a mixing bowl.
