Ingredients
Method
Rendering the Protein Base
- Heat the 2 tablespoons of olive oil in a large, heavy-bottomed soup pot or Dutch oven over medium heat.
- Add the sliced Italian sausage and sear aggressively until browned on all sides, about 5 minutes.
- Use a slotted spoon to remove the browned sausage from the pot, leaving the rich, rendered pork fat behind.
The Aromatic Sweat
- Add the diced onion and carrots directly into the rendered fat. Cook, stirring occasionally, until the vegetables soften and begin to caramelize, about 8 minutes.
- Add the diced zucchini and yellow squash, cooking for another 5 minutes until they begin to release their moisture.
- Stir in the diced poblano peppers and minced garlic, blooming the aromatics in the hot oil for 5 minutes more.
Building the Broth
- Pour the diced tomatoes and the 4 cups of beef stock directly into the pot, scraping up any browned bits from the bottom.
- Season the broth aggressively with the dried oregano, kosher salt, and coarse black pepper. Bring the liquid to a rolling simmer.
- Return the browned sausage to the pot.
The Parmesan Rind Emulsion
- Tuck the Parmesan cheese rind directly into the simmering broth. (As the rind slowly melts, it will release profound, salty umami notes and naturally thicken the soup).
- Fold the chopped kale into the pot. If the liquid does not fully cover the dense vegetables and greens, add a splash of water or extra beef stock.
- Reduce the heat to low, cover partially, and simmer for at least 45 minutes to allow the flavors to marry and extract.
The Pasta Integration
- Taste the broth and adjust the seasoning with additional salt and pepper if necessary.
- Stir the dry elbow macaroni directly into the simmering soup. Cook for 10 to 12 minutes, or until the pasta absorbs the savory broth and becomes plump and tender.
- Remove and discard the remnants of the Parmesan rind.
- Ladle the hot, thick minestrone into deep bowls, serving immediately with a heavy garnish of freshly grated Parmesan cheese and chopped basil.
