This one-pan Sausage and Romesco is Whole30-friendly, paleo, and takes about 30–40 minutes from start to finish. Everything cooks together in a single roasting pan, which makes cleanup quick and easy—always a bonus on busy nights.
It works as a fast weeknight dinner and can also be dressed up as a main course when you have guests. If you prefer to plan ahead, make the Romesco sauce earlier in the day and reheat it before serving; then simply roast or grill the sausages when guests arrive.
I’ve been leaning on this recipe for weeks because it’s so dependable. Each time I make it I want to share it on social media, but it felt right to put the finished recipe here first. The method is forgiving and the flavors are bold without requiring complicated techniques or hard-to-find ingredients.
Choose high-quality sausages without fillers or unnecessary additives. A good hot Italian-style sausage or any flavorful sausage you enjoy will work well. Look for intact casings so the sausages keep their juices while roasting; sausages with split or weak edges can dry out. The easiest way to get perfect results is to use an instant-read meat thermometer and remove the sausages from the oven when they reach a safe internal temperature.
The Romesco sauce is the highlight: bright, smoky, and quick to prepare. It’s made from just a handful of ingredients and can be whipped up while the sausages roast. Despite its simplicity, the sauce adds a vibrant, restaurant-quality finish that makes the whole dish feel special.
You can store leftover Romesco in the refrigerator for about five days; it tastes great cold or gently warmed. For longer storage, freeze the sauce for up to six months in a sealed container, leaving a little headspace for expansion. Thaw in the refrigerator or at room temperature before serving. Making a larger batch when red peppers are in season and freezing portions is a convenient way to have ready-made sauce on hand.
Because the recipe relies on just a few good ingredients, quality matters. Use fresh produce and flavorful sausages—there’s nowhere to hide, and the results will be worth the little extra effort.
One-Pan Whole30 Roasted Sausage and Romesco
Servings: 3 people
Ingredients
- 6–8 hot Italian sausages (or your preferred sausages)
- 2 large red bell peppers, sliced into 1″ strips
- 1 medium red onion, sliced into 1″ strips
- 3 cloves garlic, smashed and peeled
- 1 tsp dried oregano (or 1 tbsp fresh oregano, chopped)
- 1 tbsp sherry vinegar
- 4 tbsp extra virgin olive oil (EVOO), divided
- Kosher salt and freshly cracked black pepper, to taste
- Fresh parsley leaves, for garnish
Instructions
- Preheat the oven to 425°F (220°C).
- Place the red peppers, red onion, garlic, and oregano in a roasting tray. Season lightly with salt and pepper and drizzle with 2 tablespoons of EVOO. Toss to coat and spread the vegetables in an even layer across the bottom of the tray.
- Lay the sausages on top of the vegetables. Brush the sausages lightly with a bit of EVOO. Roast in the oven for 30–35 minutes, turning the sausages halfway through cooking, until the sausages reach an internal temperature of 160°F (71°C) on an instant-read thermometer.
- Remove the tray from the oven. Transfer the sausages to a plate and set aside. Pour the roasted vegetables and any rendered juices into a high-speed blender. Add 1 tablespoon of sherry vinegar.
- Blend on medium until smooth and creamy. With the blender running, slowly drizzle in the remaining 2 tablespoons of EVOO to emulsify the sauce. Taste and adjust seasoning with salt and pepper if needed.
- To serve, spoon the Romesco onto a serving dish, slice the sausages in half, and arrange them over the sauce. Garnish with fresh parsley and a final drizzle of EVOO.
This simple, one-pan meal pairs well with a crisp green salad or roasted seasonal vegetables. Leftover Romesco makes a great spread for sandwiches, a dip for vegetables, or a sauce for grilled fish and chicken.
