Rustic Vegetable & Andouille Chicken Sausage Pasta Sauce

Prep: pulse vegetables in Cuisinart

Roughly chop all vegetables using a Cuisinart food processor on pulse. You want irregular, chunky pieces — not purée. Do the harder vegetables (peppers, carrots, celery) first; pulse softer ones (zucchini, squash, eggplant) separately so nothing becomes mush. Spinach goes in by hand at the end.

Sauté onion — aromatic base

Heat avocado oil in a large heavy-bottomed pot or Dutch oven over medium to medium-high heat. Avocado oil's high smoke point (~520°F) handles this stage well. Add onion alone. Cook 5–6 minutes, stirring occasionally, until softened and translucent.

Add carrots, celery, and garlic

Add carrots, celery, and minced garlic. Sauté another 5–7 minutes. Garlic goes here — not at the start — to prevent burning. The carrots provide natural sweetness that helps balance acidity later.

Brown the Andouille

Slice or crumble the Andouille sausage into the pot. It's fully cooked — you're building fond and releasing its smoked, Cajun spice into the fat. Cook 3–4 minutes until browned. This is a major flavor driver for the whole sauce.

Add remaining vegetables

Add peppers, zucchini, yellow squash, and eggplant. Continue sautéing 8–10 minutes until all vegetables are softened and fragrant. Add spinach last and stir until wilted, about 2 minutes.

Caramelize the tomato paste

Stir in the tomato paste directly into the vegetable mixture. Cook it for 2–3 minutes before adding any liquids — this caramelizes the paste, deepens its umami, and meaningfully reduces the raw sharpness it would otherwise add.

Build the sauce

Add all tomatoes (Roma and beefsteak), chopped or crushed by hand, along with the fresh basil — it goes in with the tomatoes and cooks into the sauce. Pour in tomato juice and chicken broth. Add Worcestershire sauce and Italian seasoning. Taste before adding paprika — the Andouille already provides smoke and spice. Add salt and black pepper. Stir well to combine.

Reduce and balance acidity

Bring to a gentle boil, then reduce to a low simmer. Leave partially uncovered to reduce. Stir in 1 tbsp brown sugar early in the reduction. After 20 minutes, taste: if still sharp, add baking soda ⅛ tsp at a time — stir, watch for brief foaming (that's acid neutralizing), wait 30 seconds, then taste again. You may need 3–4 pinches. Simmer 45–60 minutes total. Acidity mellows significantly with time. Add a second tbsp of brown sugar only if still needed at the end.

Grill reduction (preferred method)

Transfer the sauce to a full hotel pan. Place on a grill set to low heat — around 275–300°F — uncovered. Let it reduce for approximately 2 hours, stirring occasionally. The open-air evaporation concentrates flavors without the scorching risk of stovetop reduction, and the gentle, even heat mellows acidity naturally. The sauce is ready when it reaches a rich, thick consistency and the liquid has reduced by roughly a third.

Finish and serve

Off the heat, stir in 2 tbsp unsalted butter — this rounds out remaining sharpness and gives the sauce a glossy, restaurant-quality finish (mantecatura). Taste for final seasoning. Optional: finish with a drizzle of EVOO. Serve over pasta of your choice.
