Sauté the bacon: Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add the thick-cut bacon and cook until crispy, about 3-4 minutes. Remove and set aside. Leave 3 tablespoon of the oil in the pan. See note in note section.
Cook the pasta: While the sauce simmers, cook your pasta according to the package instructions 2 minutes short of al dente. Reserve 2 cups of pasta water before draining.
Bloom the spices: Turn the head to medium and add in the red pepper flakes (or Calabrian chili) to the pan. See note in notes section. Add the oregano and sauté for 1 minute.
Add the onion, and lightly crushed garlic cloves (you just want to hit the clove with a knife to release some of the flavor). Sauté until the onion becomes translucent and the garlic is fragrant, about 3-4 minutes.
Add the tomato paste: Stir in the sun dried tomato paste (if using) and regular tomato paste, cooking for about 2-3 minutes to deepen the flavors.
Deglaze with vodka (see note in note section): Turn off the heat and pour in ½ cup vodka to deglaze the pan, scraping up any flavorful brown bits from the bottom with a wooden spoon. Turn the heat to medium and simmer for 5 minutes until the vodka reduces.
Add the cream: Stir in the heavy cream and simmer for another 2-3 minutes until the sauce thickens slightly. Season with salt and black pepper to taste. Fish out the whole garlic cloves.
Blend (Optional): I have a picky eater so I blended my sauce and then returned it to the pan.
Finish the sauce: Toss the cooked pasta in the sauce, adding some of the reserved pasta water to adjust the sauce’s consistency. Stir in the grated pecorino and parmesan until melted.
Serve: Spoon the pasta into bowls and top with a dollop of ricotta, a sprinkle of parmesan, and freshly chopped parsley or basil.
