I’ve transformed the rich, creamy classic Penne alla Vodka into a low FODMAP, dairy-free sauce that’s decadent without the heaviness. Roasted tomatoes and carrots are blended into a silky orange sauce that replaces cream, making it ideal for serving over gluten-free pasta.
This version of vodka sauce is a staple in my kitchen. It’s lighter than the traditional cream-based recipe and relies on roasted vegetables for body and sweetness. The carrots and a small amount of fennel add natural creaminess and balance the tomatoes’ acidity, so the sauce tastes lush without any dairy, nuts, or coconut-based thickeners.
Roasting the tomatoes, carrots, and fennel concentrates their flavors and caramelizes their natural sugars. Once blended with vegetable stock or water, the mixture becomes a velvety sauce that clings beautifully to pasta. If you aren’t following a low FODMAP protocol, you can add garlic or shallot to the roasting pan, but this version showcases how simple ingredients can produce a deeply satisfying sauce while remaining gentle on sensitive stomachs.
Most store-bought sauces include garlic and onion, both high FODMAP ingredients, and many vodka sauces are loaded with heavy cream. This recipe avoids those pitfalls while delivering a satisfying, restaurant-quality result. The reduced tomato content and the sweetness from roasted carrots make it a good option for people sensitive to acidity.
To prepare, spread the tomatoes, carrots, and fennel on a sheet pan, season, drizzle with olive oil, and roast until caramelized. Blend the vegetables with stock or water until smooth—the texture should be thick and velvety. Store any leftover sauce in the refrigerator for up to two weeks.
This sauce pairs perfectly with 100% gluten-free pasta—brown rice penne or spaghetti work especially well. The recipe below is scaled to coat about 12 ounces of pasta and serve four people when paired with a simple salad. Because fennel is a moderate-FODMAP ingredient, this recipe uses half a medium bulb and recommends limiting a single serving to about one-third of the batch to stay within low FODMAP guidelines.
What to serve with this low FODMAP pasta:
A crisp green salad dressed with a low FODMAP vinaigrette is all you need. The light, herb-forward dressing complements the creamy roasted sauce and keeps the meal balanced and simple.
Read on for the recipe and instructions to make this healthy, low FODMAP vodka-style sauce.

Low FODMAP Vodka Pasta Sauce
print recipe
Ingredients
- 1 pound carrots about 3 large, unpeeled and cut into 1-inch chunks
- 1.5 pound vine tomatoes about 4 medium, quartered
- 1/2 fennel bulb sliced into thin wedges
- Olive oil
- Sea salt
- 1 cup vegetable stock or water
- 12 ounces gluten-free penne optional, for serving
- 1/3 cup basil leaves optional, for garnish
- Garlic-infused oil optional, for garnish
- Red pepper flakes optional, for garnish
Instructions
-
Preheat the oven to 450°F and line a sheet pan with parchment paper.
-
Arrange the tomatoes, carrots, and fennel on the sheet pan. Season with 1 teaspoon sea salt and drizzle generously with olive oil. Place vegetables cut-side down in a single layer so each piece contacts the pan, then roast.
-
Roast until the tomatoes have shriveled and released their juices and the carrots are tender, about 40 minutes. Remove from the oven.
-
Transfer the roasted vegetables to a high-powered blender with the vegetable stock or water. Puree until completely smooth, adding more liquid if needed. Store in an airtight container in the fridge for up to 2 weeks, or proceed to make pasta.
-
To prepare pasta: bring a large pot of salted water to a boil and cook the pasta according to package instructions. Reserve 1 cup of starchy pasta water before draining.
-
Return the pasta to the pot with 1 cup of the vodka-style sauce and toss, adding pasta water as needed to loosen the sauce. Add more sauce if desired and save the remainder for another meal.
-
Divide the pasta among bowls and garnish with basil, red pepper flakes, and a drizzle of garlic-infused oil if using.
