This rich and flavorful tomato sauce is inspired by an Italian chef’s recipe and perfected over intermittent cooking sessions spanning 2-3 days (with my husband’s help). The slow cooking process is essential for developing its deep, robust flavor. Remember to taste the sauce throughout and adjust the salt as needed.
Ingredients
- 1 (6 lb 10 oz) can San Marzano tomatoes (available at Costco)
- 1 large white or yellow onion, diced
- 2 teaspoons minced garlic
- 2-3 tablespoons olive oil
- 1 cup fresh basil, chopped, or 2-3 tablespoons dried basil
- 2-3 tablespoons dried oregano
- 3 tablespoons kosher salt (adjust to taste)
- 2 bay leaves
- 1 bone-in pork chop or any beef/pork bone with marrow
- 1 package Italian sausage (hot or mild, according to preference)
Equipment
- Large pot
- Potato masher
- Immersion blender
Instructions
- Sauté Aromatics
- In a large pot, heat the olive oil over medium heat.
- Add the diced onion and sauté for 3-4 minutes until it becomes translucent.
- Add the minced garlic and sauté for an additional 1-2 minutes, being careful not to let the garlic burn.
- Add Tomatoes and Seasonings
- Pour in the San Marzano tomatoes.
- Use a potato masher to break down the tomatoes into smaller pieces.
- Add the kosher salt, fresh or dried basil, dried oregano, bay leaves, and the bone-in pork chop.
- Simmer
- Bring the mixture to a boil, then reduce the heat to low and let it simmer for about 4 hours, stirring every 20-30 minutes to prevent the sauce from sticking to the bottom of the pot and burning. This step is crucial for developing deep, rich flavors.
- Blend the Sauce
- After 4 hours, remove the pork chop or bone (your dog will appreciate this treat!).
- Use an immersion blender to blend the sauce until smooth. If you prefer a chunkier texture, blend only partially.
- Taste the sauce and adjust the salt as needed.
- Add Italian Sausage
- Add the Italian sausage to the sauce and continue to simmer on low for another 3-4 hours, stirring occasionally.
- Final Touches
- Before serving, you can add pre-cooked meatballs; Jim’s Meatball Recipe to the sauce and simmer for 10-15 minutes to let the flavors meld together.
- Serve
- Serve the sauce over your favorite pasta and enjoy!
Tips
- Slow Cooking
- Cooking the sauce over multiple days in short increments helps to deepen the flavor. If you’re short on time, you can complete the process in a single day but make sure to simmer for at least 6-8 hours total.
- Adjusting Consistency
- If the sauce becomes too thick, you can add a splash of water or a bit more tomato sauce to reach your desired consistency.
- Storage
- Store the sauce in plastic containers and freeze for up to six months. It’s great to have on hand for quick meals.
Enjoy this rich, slow-cooked Italian tomato sauce over your favorite pasta, and experience the depth of flavor that comes from the extended simmering process. Buon appetito!
