    Creamy, make-ahead Low FODMAP overnight oats with lactose-free milk, chia seeds, blueberries, strawberries, and walnuts. 5 minutes prep, low-FODMAP portions, perfect for a calm-gut breakfast.

    Ingredients

    • ½ cup (45 g) rolled (old-fashioned) oats — gluten-free if needed
    • ½ cup (120 ml) lactose-free milk OR unsweetened almond milk
    • 2 tbsp lactose-free plain yogurt (optional, for extra creaminess)
    • 1 tbsp chia seeds
    • 1 tsp pure maple syrup (avoid honey & agave)
    • ¼ tsp vanilla extract
    • Pinch of cinnamon
    • Topping: ¼ cup (40 g) fresh blueberries

    Why overnight oats are great for IBS

    Rolled oats are Low FODMAP up to ½ cup (45 g) uncooked per serve (Monash). Soaking them overnight softens the starch and makes them gentler on a sensitive gut — no cooking, no fuss.

    Avoid instant oat sachets: most contain added inulin, dried apple, or honey, which are high in FODMAPs. New to portions? Use our Low FODMAP Food Checker before swapping anything in.

    Step-by-step instructions

    1. Combine the base. In a 12-oz mason jar or bowl, add rolled oats, lactose-free milk, yogurt, chia seeds, maple syrup, vanilla, and cinnamon.
    2. Stir well so the chia seeds don't clump at the bottom.
    3. Refrigerate uncovered for 10 minutes, stir once more, then seal and chill overnight (or at least 4 hours).
    4. In the morning, stir, loosen with a splash of milk if too thick, and top with blueberries, strawberries, and chopped walnuts.
    5. Eat cold straight from the jar, or warm gently in the microwave for 45 seconds.

    Serving size & FODMAP safety

    One jar = 1 Low FODMAP serving. Stay inside these tested portions:

    Ingredient Low FODMAP serve Why it matters
    Rolled oats ½ cup (45 g) uncooked Doubling pushes total fructans up
    Lactose-free milk 250 ml Regular cow's milk = high lactose
    Blueberries ¼ cup (40 g) ½ cup = moderate FODMAP
    Strawberries 10 medium (150 g) One of the safest fruits
    Walnuts 30 g Pecans (20 g) work too
    Maple syrup 2 tbsp Avoid honey & agave

    For why doubling toppings can backfire, read our FODMAP Stacking Guide.

    High → Low FODMAP swaps

    Skip (High FODMAP) Use instead (Low FODMAP)
    Cow's milk Lactose-free milk or almond milk (≤250 ml)
    Honey or agave Pure maple syrup
    Raisins / dried apple Fresh blueberries or strawberries
    Cashews / pistachios Walnuts or pecans
    Wheat-based granola Toasted oats + pumpkin seeds
    Greek yogurt Lactose-free plain yogurt

    Flavor variations (still Low FODMAP)

    • Peanut butter banana: add 1 tbsp natural peanut butter + ⅓ medium unripe banana.
    • Chocolate strawberry: stir in 1 tsp cocoa + 2 tbsp dark chocolate chips, top with strawberries.
    • Tropical: swap berries for ⅓ cup pineapple and 2 tbsp shredded coconut.
    • Coffee: stir in 1 shot cooled espresso + extra cinnamon for a mocha twist.

    Meal prep tips

    • Batch 4 jars on Sunday — they keep 4 days in the fridge. Add fresh fruit & nuts the morning of.
    • Use ½-pint mason jars so portions stay precise (no eyeballing).

    Common mistakes to avoid

    1. Using steel-cut oats — they stay hard overnight. Stick with rolled (old-fashioned) oats.
    2. Skipping the stir-after-10-min step — chia seeds clump and sink.
    3. Adding banana the night before — it browns. Slice fresh in the morning.
    4. Overdoing toppings — even Low FODMAP foods stack. Stick to the portions above.

    Practical Low FODMAP Notes for Low FODMAP Overnight Oats — Creamy 5-Minute IBS-Friendly Breakfast

    Low FODMAP Overnight Oats — Creamy 5-Minute IBS-Friendly Breakfast is most useful when the serving size stays consistent, because FODMAP tolerance often changes when portions creep upward. Use the listed servings as the starting point, then portion leftovers before storing so the meal stays predictable on busier days. If you are cooking for family members who do not follow a low FODMAP plan, keep onion, garlic, wheat-heavy sides, and high-FODMAP sauces separate at the table instead of mixing them into the main recipe.

    Ingredient notes: this recipe uses ½ cup (45 g) rolled (old-fashioned) oats — gluten-free if needed, ½ cup (120 ml) lactose-free milk OR unsweetened almond milk, 2 tbsp lactose-free plain yogurt (optional, for extra creaminess), 1 tbsp chia seeds, 1 tsp pure maple syrup (avoid honey & agave), ¼ tsp vanilla extract, Pinch of cinnamon, Topping: ¼ cup (40 g) fresh blueberries, Topping: 5 medium strawberries, sliced, Topping: 10 walnut halves (≈30 g), roughly chopped. Check packaged ingredients carefully, especially broths, spice blends, gluten-free mixes, condiments, and dairy substitutes, because garlic powder, onion powder, inulin, chicory root fiber, high-fructose sweeteners, and wheat-based thickeners can appear in small print. When unsure, choose plain versions and add flavor with garlic-infused oil, fresh herbs, citrus, ginger, chives, scallion greens, or low FODMAP spice blends.

    For IBS-friendly meal prep, cool leftovers quickly and refrigerate in shallow containers. Reheat only the portion you plan to eat, and add fresh herbs, lemon juice, or a small drizzle of garlic-infused oil after reheating to bring the flavor back without relying on high-FODMAP aromatics. If a recipe feels too rich during a flare, pair it with a simple low FODMAP side such as rice, potatoes, quinoa, lettuce, cucumber, carrots, or another tolerated vegetable.

    This recipe is intended for general low FODMAP education, not medical advice. Individual tolerance varies, so use your dietitian’s guidance and your own symptom history when deciding whether to repeat, increase, or modify a serving. During the elimination phase, keep portions conservative; during reintroduction, test one FODMAP group at a time so you can clearly identify personal triggers.

    Helpful next steps: use the FODMAP Food Checker before adding new ingredients, try the Ingredient Swap Tool when a sauce or seasoning is questionable, and save recipes that worked well so you can build a reliable rotation of breakfasts, lunches, dinners, and snacks.
