In a 6- to 8-quart slow cooker, combine the oil, onion, roasted red peppers, Calabrian chiles, garlic, oregano, red-pepper flakes, fennel seeds and tomatoes. (Crush the tomatoes by hand if using whole.) Season with 1/2 teaspoon salt and several generous grinds of black pepper. Stir well to combine, then cover and cook on high for 5 hours. (The sauce holds well on warm for up to an additional 3 hours.) Increase the heat to high if it has switched to warm. Stir in the shrimp, capers and scallions. Cover and cook until the shrimp are curled and opaque, 15 to 20 minutes, depending on size and quantity. Turn off the heat and taste the sauce. Add more red-pepper flakes and salt and pepper, if you like. Sprinkle the cheese over the top and serve, passing more Parmesan and red-pepper flakes at the table.

Warm the olive oil in a 12-inch skillet over medium-high. Add the onion, season generously with salt, and cook, stirring, until the onion is translucent, soft and starting to turn golden, 7 or 8 minutes. If necessary, decrease the heat to medium to prevent scorching. Add the garlic and cook until fragrant and softened, about 2 minutes. Stir in the oregano, red-pepper flakes and fennel seeds, then the Calabrian chiles, roasted red peppers and tomatoes. (Crush the tomatoes by hand, if using whole.) Season with salt and pepper. Bring to a simmer, adjust the heat to maintain a simmer, and cook for about 5 minutes to slightly reduce the sauce and blend the flavors. Add the shrimp, scallions and capers, and cook until the shrimp are curled, pink and opaque, 3 to 7 minutes, depending on size and quantity. Turn off the heat and taste the sauce. Add more red-pepper flakes, salt and pepper, if you like. Sprinkle the cheese over the top and serve, passing more Parmesan and red-pepper flakes at the table.
