Many pasta sauces rely on tomatoes or vinegar, both of which can be high in histamine. This version skips them entirely, using roasted red bell peppers and carrots for a naturally sweet base. Coconut milk adds creaminess, while thyme and rosemary give an anti-inflammatory, aromatic flavor. It’s a perfect gut-friendly sauce for pairing with gluten-free or fresh pasta.
Ingredients Needed
- 2½ large red bell peppers: chopped into chunks.
- 1½ large carrots: halved lengthwise.
- 1 tbsp olive oil: cold-pressed.
- ½ can coconut milk: unsweetened, full-fat for creaminess.
- 1 tsp dried thyme: for gentle herb flavor.
- 2 small rosemary sprigs: fresh.
- 1 garlic clove: roasted for mildness.
- Pinch salt: adjust to taste.
- Pinch white pepper (optional): gentler than black pepper.
How To Make Low Histamine Pasta Sauce
Preheat Oven: Set oven to 390°F (200°C) and line a baking sheet with parchment paper.
Roast Vegetables: Place bell pepper chunks and halved carrots on the sheet. Sprinkle with thyme, add rosemary sprigs, and drizzle with olive oil. Roast for 20–30 minutes until soft.
Cool & Prep: Remove rosemary sprigs and discard. Squeeze roasted garlic from its skin. Let vegetables cool slightly.
Blend Sauce: Add roasted vegetables, garlic, coconut milk, salt, and optional pepper to a blender or food processor. Blend until smooth and creamy.
Serve: Toss with freshly cooked pasta and serve immediately.

Recipe Tips
- Skip the vinegar — it’s high histamine and not needed for flavor.
- For a thicker sauce, reduce coconut milk slightly.
- This sauce also works as a vegetable dip or topping for chicken.
- Always use fresh red peppers, not roasted jarred ones (they are often aged or vinegar-packed).
How to Store & Reheat
- Room Temperature: Serve immediately after blending.
- Fridge: Store in a sealed glass jar for up to 12 hours.
- Freezer: Not recommended for low histamine diets, as freezing can increase histamine levels.
