Savory Chicago Spaghetti Sauce

This hearty Chicago Spaghetti recipe delivers the authentic flavors of a classic Windy City meat sauce that's rich, satisfying, and packed with Italian-American heritage. The combination of sausage and beef creates a robust sauce that clings perfectly to thick spaghetti strands.

I first made this Chicago Spaghetti during a brutal Midwest winter when comfort food was essential. Since then, it's become my go-to dish whenever friends gather at my home – there's something about this sauce that creates instant nostalgia even for first-time tasters.

• Italian sausage: Provides the signature Chicago flavor profile with its fennel and herb notes
• Ground beef: Adds textural contrast and depth to the meat component
• Green bell pepper: Contributes a slightly sweet crunch essential to authentic Chicago sauce
• Crushed tomatoes: Forms the base of the sauce with balanced acidity
• Tomato paste: Intensifies the tomato flavor and thickens the sauce beautifully
• Sugar: Counterbalances the acidity of the tomatoes for perfect harmony
• Dried herbs: Infuse the sauce with classic Italian flavors that bloom during simmering
• Parmesan cheese: Adds umami richness and helps the sauce adhere to pasta
• Thick spaghetti: Stands up to this hearty sauce better than thinner varieties

Step-by-Step Instructions

Prep the Pasta:

Bring a large pot of water to a rolling boil. Add a generous amount of kosher salt until it tastes like seawater. Cook thick spaghetti until al dente according to package directions. Reserve 1/2 cup pasta water before draining for potential sauce adjustment later.

Brown the Meats:

Heat olive oil in a large heavy-bottomed pot over medium-high heat until shimmering. Add Italian sausage and ground beef, breaking into small pieces with a wooden spoon. Cook until well-browned with some crispy edges, about 7-8 minutes. This caramelization creates foundational flavor.

Build the Aromatics:

Add diced onion, minced garlic, and bell pepper to the browned meat. Reduce heat to medium and cook until vegetables soften but don't brown, approximately 3-4 minutes. The vegetables should release moisture and pick up the fond from the bottom of the pot.

Create the Sauce Base:

Stir in tomato paste and cook for 2 minutes, allowing it to caramelize slightly. Add sugar and all dry seasonings, stirring constantly for 30 seconds to bloom the spices. The mixture will become fragrant and deeply colored.

Simmer to Perfection:

Deglaze the pot with water, scraping up any browned bits from the bottom. Add crushed tomatoes and stir to combine. Bring to a gentle simmer, then reduce heat to low. Cook uncovered for 30 minutes, stirring occasionally. The sauce should thicken and develop complex flavors.

Final Assembly:

Taste sauce and adjust seasoning with salt and pepper. Add the drained spaghetti and parmesan cheese directly to the sauce. Toss thoroughly using tongs until every strand is coated. If sauce seems too thick, add reserved pasta water a tablespoon at a time.

My grandmother always insisted on adding a pinch of sugar to tomato sauces, a trick I initially resisted but now appreciate. The sugar doesn't make the sauce sweet – it balances the acidity and brings out the natural sweetness of the tomatoes in a way that creates remarkable depth.

Make-Ahead Magic

Chicago Spaghetti sauce improves with time, making it perfect for advance preparation. You can prepare the sauce up to three days before serving and refrigerate in an airtight container. When ready to serve, gently reheat the sauce, adding a splash of water if needed to loosen, then toss with freshly cooked pasta.

Vegetarian Adaptation

This classic can be transformed into a delicious meatless version. Replace the meats with 16 ounces of chopped mushrooms and 1 cup of diced zucchini. Cook mushrooms until their liquid releases and evaporates, allowing them to brown slightly before continuing with the recipe. Add 1/4 teaspoon of smoked paprika to achieve deeper flavor.

Authentic Chicago Touches

While spaghetti with meat sauce is beloved across America, Chicago versions typically feature a slightly sweetened sauce, generous proportion of meat, and the addition of green peppers. Locals often serve this with a side of garlic bread brushed with butter and sprinkled with grated parmesan, then broiled until golden.

Weekend Entertaining

Turn this dish into an impressive dinner party centerpiece by serving it with a Caesar salad, garlic bread, and a bottle of Chianti. For a true Chicago experience, follow with a dessert of cannoli or spumoni ice cream from one of the city's historic Italian bakeries.
