What this recipe does for you.
A weeknight low-FODMAP pasta that tastes like the real thing. Garlic-infused oil instead of garlic, gluten-free or spelt pasta, a bright tomato sauce. 30 minutes, no gut afternoon to follow.
Why this works
Every recipe on this site ships with an explanation of the technique decisions, why sear then braise, why the acid goes in at the end, why the fat renders before the aromatics. The method below is those decisions, in order.
Garlic-infused olive oil
This is the whole trick of low-FODMAP cooking. The fructans that trigger most people live in the flesh of garlic and onion, not in the oil they flavor. Infuse a good olive oil with smashed garlic cloves over low heat, then fish the cloves out, and you keep every bit of the flavor and none of the FODMAPs. Buy a commercial garlic-infused oil (FODY or Garlic Gold) if you want it foolproof, or make your own in five minutes. Do not skip this and just leave garlic out; the dish tastes flat without it.

Method
Make the garlic-infused oil first, low and slow
Quarter cup extra-virgin olive oil, four garlic cloves smashed but whole, in a cold skillet over low heat. Let them sizzle gently for 5 minutes until the oil smells like a pizzeria and the cloves turn pale gold, then lift every clove out and discard. The flavor is in the oil now. Whole cloves are easy to remove; do not mince, because tiny bits you cannot fish out reintroduce the fructans you are avoiding.
Use the green tops of scallions, not the white bulbs
The white and pale-green bulb of a scallion is high-FODMAP; the dark green tops are not. Slice a small bunch of green tops and add them to the infused oil for an oniony backbone that is safe. This is the second half of the garlic-and-onion swap, and together they make the sauce taste like an ordinary marinara rather than a deprivation dish.
Pick the right pasta: gluten-free or true sourdough spelt
Wheat pasta is high in fructans. Most rice, corn, or quinoa gluten-free pastas are low-FODMAP at a one-cup cooked serving (Monash tests them this way). Salt the water well, and pull gluten-free pasta a minute early because it goes from firm to mushy fast. Reserve a cup of the starchy cooking water before you drain; it is what brings the sauce together at the end.
Canned tomatoes are fine, tomato paste in moderation
A 14-ounce can of crushed tomatoes is low-FODMAP at this serving size. Tomato paste concentrates FODMAPs, so cap it at one tablespoon for the whole pan. Add the tomatoes to the infused oil and scallion tops, a teaspoon of dried oregano, a pinch of chili flakes, and simmer 12 minutes until it thickens and the raw-tomato edge cooks off.
Season with salt at the end, finish with the pasta water
Salt the sauce at the end, after it has reduced, so you do not over-salt a shrinking pan. Drop the drained pasta straight into the sauce with a splash of the reserved cooking water and toss hard for a minute over heat. The starch in the water emulsifies the oil and tomato into a glossy sauce that clings instead of sitting in a puddle.
Add a protein that fits the pattern
As written this is a 12g-protein vegetarian plate. Stir in a tin of drained chickpeas (rinse well, a quarter cup cooked is the Monash low-FODMAP threshold) for plant protein, or fold in cooked ground turkey or shredded chicken to push it past 30g. Both keep the dish low-FODMAP. A handful of cooked shrimp tossed in at the end is the fastest option.
Finish with hard cheese and fresh basil, off dairy-free days
Aged hard cheeses like Parmesan and pecorino are naturally low in lactose because the aging breaks it down, so a grating over the top is low-FODMAP for most people. It pushes the dish off the dairy-free tag, so leave it for strict days. Tear fresh basil over the hot pan at the table; the cooked oregano is the body, the raw basil is the lift.
Mind the serving size, that is what keeps it low-FODMAP
Low-FODMAP is about dose, not banned foods. One cup of cooked gluten-free pasta, a quarter cup of chickpeas, one tablespoon of tomato paste; stack three high-end servings on one plate and you can tip over the threshold even with safe ingredients. Plate four honest portions from this pan rather than two large ones, and the math stays on your side.

Frequently asked
- Why can't I just leave the garlic and onion out instead of infusing oil?
- You can, but the dish tastes thin and flat, and that is why most people quit low-FODMAP cooking. The compounds that trigger symptoms are the fructans in the flesh of garlic and onion, and they are water-soluble, not oil-soluble. Cooking whole cloves in oil and removing them transfers the aroma without the fructans. It is the single technique that makes low-FODMAP food taste normal, which is the difference between a diet you follow and one you abandon.
- Is gluten-free pasta automatically low-FODMAP?
- Usually, but check the label. Plain rice, corn, or quinoa pastas are low-FODMAP at a one-cup cooked serving and Monash University has tested several brands. Some gluten-free pastas add legume flours (chickpea, lentil, soy) that raise the FODMAP load, so read the ingredients. You do not strictly need gluten-free pasta to be low-FODMAP; traditional sourdough spelt is also tolerated by many because the long ferment breaks down fructans. The point is fructans, not gluten.
- Are tomatoes low-FODMAP?
- Fresh and canned tomatoes are low-FODMAP at normal serving sizes; a half-cup of canned tomatoes sits comfortably under the threshold. Tomato paste is more concentrated, so keep it to about a tablespoon for the pan, and sun-dried tomatoes climb higher still, so use them sparingly. The crushed-tomato base in this recipe, split across four servings, keeps each plate in the safe range.
- How do I add protein without breaking the low-FODMAP rules?
- Plain cooked meats, poultry, fish, and eggs have no FODMAPs, so shredded chicken, ground turkey, or shrimp are all free additions and the easiest way to reach 30g protein. Canned chickpeas work too if you rinse them and keep to a quarter-cup cooked per serving, which is the Monash low-FODMAP limit; more than that and the GOS content adds up. Avoid pre-marinated proteins, which usually hide garlic and onion powder.
- Can I make this dairy-free and still get the cheesy finish?
- Yes. Skip the Parmesan to keep the dish dairy-free as tagged. For a similar savory, salty top note, use a tablespoon of nutritional yeast or a few toasted pine nuts blitzed with salt. Hard aged cheeses are actually low-FODMAP because aging removes most of the lactose, so the cheese is fine for FODMAP reasons; the dairy-free tag is the only thing it changes.
- How long does it keep, and does it reheat well?
- Three to four days in the fridge in a glass container. Gluten-free pasta firms up cold and can go slightly grainy on reheat, so add a splash of water and warm it gently on the stovetop rather than blasting it in the microwave. The sauce itself freezes well for three months; make a double batch of just the sauce and cook fresh pasta to order, which gives the best texture.
