Bring a large pot of salted water to a boil. Cook pasta shells until al dente then drain and set aside. Combine 1 cup frozen butternut squash and 2 tsp olive oil in a large microwave-safe bowl. Cover and microwave for 2-4 minutes or until squash is tender. Mash with a fork and set aside.
Add ⅔ cup whole milk ricotta cheese, ½ tsp onion powder, ½ tsp oregano, ¼ tsp salt, ¼ red pepper flakes to the mashed squash and stir together until smooth.
Spread 1 cup marinara over the bottom of a Suvie pan. Fill 15 jumbo pasta shells with filling and arrange in Suvie pan seam side down.
