Low FODMAP Lemon Poppy Seed Zucchini Muffins
Moist, tender muffins bursting with bright lemon flavor and hidden vegetables—perfect for breakfast on the go or an afternoon snack that's gentle on your gut.
These muffins are designed to be Low FODMAP when consumed as one muffin per serving. The gluten-free flour blend eliminates wheat-based FODMAPs, while lactose-free milk removes dairy concerns. Garlic-infused oil provides flavor without FODMAPs since the fructans don't transfer to oil. Zucchini is Low FODMAP in the portions used here (about 65g per muffin). Poppy seeds are Low FODMAP. Lemon zest and juice are safe. If using almond milk instead of lactose-free milk, be mindful that almonds become moderate FODMAP above 10 nuts (about 24g), so limit almond milk to ¼ cup per serving.
There's something magical about baking with zucchini. This humble summer squash transforms into the secret ingredient that keeps these muffins incredibly moist without adding any vegetable flavor whatsoever. Combined with the bright, sunny notes of fresh lemon zest and the delicate crunch of poppy seeds, these Low FODMAP muffins are a revelation for anyone following a gut-friendly diet who thought they'd have to give up delicious baked goods forever.
What makes these muffins particularly special for FODMAP followers is their careful balance of ingredients. We use a blend of gluten-free flours that provide structure without the wheat-based FODMAPs, while lactose-free milk and a touch of garlic-infused oil keep everything beautifully tender. The zucchini not only adds moisture but also contributes valuable nutrients and fiber that's gentle on sensitive digestive systems. The lemon zest provides natural brightness without any added sugars or honey that might trigger symptoms.
These muffins are incredibly versatile—enjoy them warm from the oven with a pat of lactose-free butter, pack them in lunchboxes for a midday treat, or freeze them individually for quick grab-and-go breakfasts throughout the month. The poppy seeds add a subtle nutty flavor and a delightful textural contrast, while the lemon keeps everything tasting fresh and vibrant. Best of all, they're so delicious that no one will ever guess they're designed for sensitive stomachs.

👨🍳 Instructions
- 1
Prepare the Pan and Dry Ingredients
Preheat your oven to 350°F (175°C) and line a 9-cup muffin tin with paper liners or grease well with cooking spray. In a large mixing bowl, whisk together the gluten-free flour blend, baking powder, baking soda, salt, and poppy seeds until evenly combined. Set this aside while you prepare the wet ingredients.
⏱️ 5 min - 2
Mix the Wet Ingredients
In a separate medium bowl, beat the eggs and sugar together with a whisk or electric mixer until the mixture becomes pale and slightly fluffy, about 2 minutes. Add the garlic-infused oil, lactose-free milk, lemon zest, and lemon juice, whisking until everything is smoothly combined and the mixture looks cohesive.
⏱️ 3 min - 3
Prepare the Zucchini
Grate the zucchini using the large holes of a box grater. Place the grated zucchini in a clean kitchen towel or several layers of paper towels and squeeze firmly to remove as much excess moisture as possible—this step is crucial to prevent soggy muffins. You should have about 150g (1½ cups) of squeezed zucchini.
⏱️ 4 min - 4
Combine Wet and Dry
Pour the wet ingredient mixture into the bowl with the dry ingredients. Using a rubber spatula or wooden spoon, gently fold everything together until just combined—you should still see a few small streaks of flour. Avoid overmixing, as this can make the muffins tough. Gently fold in the prepared zucchini until evenly distributed throughout the batter.
⏱️ 3 min - 5
Fill and Bake
Divide the batter evenly among the 9 muffin cups, filling each about three-quarters full. The batter should be thick but pourable. Bake in the preheated oven for 22-26 minutes, or until the tops are golden brown and spring back when lightly touched, and a toothpick inserted into the center comes out clean or with just a few moist crumbs.
⏱️ 25 min - 6
Cool and Serve
Remove the muffin tin from the oven and let the muffins cool in the pan for 5 minutes. Then transfer them to a wire rack to cool completely. These muffins are delicious served warm or at room temperature. Store in an airtight container at room temperature for up to 3 days, or freeze individually wrapped for up to 3 months.

🔬 The Science Behind This Recipe
Why This Recipe Works for Your Gut
These muffins are designed with digestive comfort in mind, featuring ingredients that are naturally gentle on sensitive stomachs. Zucchini is a standout ingredient for IBS-friendly baking because it contains high water content and soluble fiber that helps maintain regular digestion without triggering symptoms. Unlike high-FODMAP vegetables, zucchini is low in fermentable carbohydrates, meaning it won't cause the gas and bloating that many people with IBS experience. The moisture it adds to these muffins also means you need less fat, making them easier to digest overall.
Gluten-free flour is essential here because wheat contains fructans, a type of carbohydrate that can ferment in the gut and cause discomfort for many people. By using a gluten-free blend, you're avoiding this common trigger while still achieving a light, fluffy texture. The lemon adds brightness and flavor without any digestive concerns—citrus fruits are generally well-tolerated and can actually aid digestion by stimulating digestive enzymes. Poppy seeds contribute a pleasant crunch and provide small amounts of fiber without overwhelming your system.
The garlic-infused oil is a clever workaround that deserves special mention. While garlic cloves themselves are high in fructans, the infusion process transfers only the flavor compounds into the oil, not the problematic carbohydrates. This means you get all the savory depth of garlic without any of the digestive distress. It's these thoughtful substitutions that make low-FODMAP baking both delicious and gut-friendly, allowing you to enjoy treats without compromise.
