One-Pot Spicy Rigatoni

I’m not a full convert, but I do dig this whole one-pot recipe craze. Especially with pastas, I find the noodles are particularly infused with flavor. We were inspired by this recipe, but made a few changes. I imagine it’s great with the chicken, but we’ve only ever had it without and it has never disappointed.

2 T olive oil
2 shallots, finely chopped
5 cloves garlic, smashed and chopped
2 roasted red bell peppers, roughly chopped
2 T tomato paste
1/2 c dry sherry
1 28 oz can stewed tomatoes
2 c water
2 T fresh oregano, finely chopped (or 2 t dried)
2 pinches dried red pepper flakes (3 if you like it spicy)
1/2 t salt
500 g Rigatoni (or other short pasta, tubes would be best)
1 T butter
10-15 basil leaves, torn
1/2 c Grana Padano, grated
3 T cream

In a deep pot, heat oil over medium-high heat. Sauté shallots and garlic until tender, then add peppers and cook for 2 minutes. Stir in tomato paste and cook until it begins to smell caramelized, then deglaze pot with sherry. Add tomatoes and break them up with a spatula. Add the water, oregano, pepper flakes and salt and bring to a boil.

Add the pasta and cook, stirring frequently, for 10-15 minutes or until almost tender. Turn heat down to low, add butter and basil. When butter is completely melted, add cheese and cream, stirring until integrated. Simmer for 5 minutes more, stirring all the time, then remove from heat. Let stand for a couple of minutes, then serve.
