Rich, Slow-Simmered Italian Bolognese with Rigatoni

This rigatoni bolognese is the kind of pasta sauce you make when you want something extra special. It simmers for a full three hours, developing deep, slow-cooked flavor from ground beef, pork, and chopped chicken livers (you'll never detect them, but wow do they add richness). Fresh thyme and rosemary keep it bright and aromatic. Tossed with rigatoni and Parmesan, it's pure comfort in a bowl.

Equipment

Ingredients

  • 4 Tbsp unsalted butter
  • 2 Tbsp extra virgin olive oil
  • 1 cup sweet onion, finely diced, about 1 medium or ½ large
  • 1 cup carrot, finely diced, about 1 large
  • 1 cup celery, finely diced, about 2 stalks
  • 2 lbs ground beef
  • 1 lb ground pork
  • 2 tsp kosher salt
  • ½ tsp freshly ground black pepper
  • 1 ½ cups red wine, such as Rioja
  • 1 cup whole milk
  • 2 cups low sodium chicken stock or vegetable stock
  • 1 (28 oz) can whole San Marzano plum tomatoes
  • 2 dried bay leaves
  • ½ lb chicken livers, rinsed, drained, and trimmed of any fat or connective tissue, very finely chopped
  • 2 Tbsp fresh rosemary, finely chopped
  • 1 Tbsp fresh thyme, finely chopped
  • 1 lb rigatoni
  • lemon zest, for serving
  • Freshly grated Parmigiano Reggiano, for serving
  • Flaky sea salt

Instructions

  • Make the soffrito. Finely chopped onion, carrot, and celery. Yes, you can do this in a food processor. No, I don't generally. I like the soffrito to have some texture, not turn into pulp.
  • Sweat the veggies. Heat olive oil and butter in a large dutch oven over medium-low to medium heat. Add the onion and cook for 3 minutes until translucent. Raise the heat to medium, then add the carrot and celery. Cook for an additional 5 minutes, stirring occasionally.
  • Brown the meat. Increase the heat to medium-high, then add the ground beef and ground pork. Season the meat immediately with 2 tsp Kosher salt and ½ tsp black pepper. Let this cook about 8-10 minutes, stirring often and breaking up the meat with a wooden spoon or spatula.
  • Deglaze the pan. Pour in red wine, allowing it to reduce and evaporate, about 3-4 minutes. Don't worry, all the flavor stays behind!
  • Skim the fat. Once the wine reduces, you'll see excess fat float to the top of the pan. Use a spoon to skim the fat, then discard. This will yield about ¾-1 cup of fat. Removing this makes the bolognese sauce less greasy.
  • Add remaining liquid. Pour in the whole milk and chicken stock. Next, crush the tomatoes with your hands directly into the pot. Add two bay leaves and—the most important part of the recipe!—½ lb finely chopped chicken livers.
  • Simmer low and slow. Allow the sauce to simmer over low heat for 3 hours, checking on it and stirring every 30 minutes or so. If the heat is at a proper simmer, you shouldn't need to add any additional liquid at all.
  • Finish the sauce. Remove the bay leaves, then add freshly chopped rosemary and thyme. Taste and adjust seasoning, as needed.
  • When ready to serve, cook pasta. Cook rigatoni or other pasta according to package directions for al dente, meaning just slightly undercooked by 1-2 minutes. This is important! Before draining, reserve 1 cup pasta cooking water. Drain pasta (don't rinse it!) and set aside.
  • Cook with pasta in the sauce. Transfer as much bolognese as you want to a large skillet. Heat over medium high heat until bubbly. Add al dente rigatoni or other pasta shape directly to the pan. Cook, stirring or shaking the pan often, so that each piece of pasta is completely coated with sauce.
  • To serve. Add a couple tablespoons (more, if making a lot of pasta) of the reserved pasta cooking water. The starch from cooking the pasta will thicken the sauce and bring it to life! Divide pasta between bowls, then serve with a drizzle of extra virgin olive oil, grated lemon zest, freshly grated Parmesan, and a pinch of flaky sea salt!

Notes

  • If you omit the chicken livers (please don't!) you will likely need to add additional Kosher salt. Taste and adjust as needed.
  • Make-ahead: The sauce tastes even better after 1-2 days. Keep refrigerated for 3-4 days.
  • Reheating: Warm in a skillet until bubbly, then toss in cooked al dente pasta and finish with Parmesan and lemon zest.
  • To freeze, cool completely, store in an airtight container, then freeze for up to 6 months. Thaw overnight or warm gently in a skillet with a splash of stock. Do not free pasta mixed with the sauce.
