Vegan Pumpkin Overnight Oats

These vegan pumpkin overnight oats are an easy make-ahead breakfast made with pumpkin puree, rolled oats, dairy-free milk, ground flaxseed, maple syrup, pumpkin pie spice, and a touch of peanut butter. These creamy pumpkin spice overnight oats have plenty of warm fall flavor and take about 5 minutes to prepare before chilling overnight.

Ground flaxseed helps thicken the oats without chia seeds, while the pumpkin puree and peanut butter add richness without yogurt. Enjoy them cold for breakfast, as a snack, or add a dollop of coconut cream for a simple dessert.

Ingredient notes and substitutions

The recipe uses simple ingredients, but please see the recipe card below for exact measurements.

Old-fashioned oats - Rolled oats give the best texture for overnight oats. Quick oats can become mushy, and steel-cut oats are not a good substitute for this recipe. For pumpkin oatmeal made with steel-cut oats, try my pumpkin steel-cut oatmeal.

Dairy-free milk - Use your favorite plant-based milk, such as almond, oat, soy, cashew, or refrigerated coconut milk (not full-fat canned). I prefer a 1:1 ratio of milk to oats, but you can always adjust that for your preferences.

Pumpkin puree - Use plain pumpkin puree, not pumpkin pie filling. Pumpkin puree can vary in thickness by brand, and homemade puree may be thinner and more watery than canned. I have not tested this recipe with homemade pumpkin puree. Store leftover pumpkin in an airtight container in the refrigerator and use it in oil-free vegan pumpkin muffins, pumpkin baked oatmeal, pumpkin steel-cut oatmeal, smoothies, or another batch of overnight oats.

Natural peanut butter - Adds richness and depth of flavor to the overnight oats. Almond butter can be used instead. For more oatmeal recipes with peanut butter, try banana cinnamon overnight oats or chocolate peanut butter overnight oats.

Pure maple syrup - Adds sweetness and pairs well with the pumpkin and warm spices. Adjust it to taste, or substitute agave syrup if needed.

Ground flaxseed - Helps thicken the oats as they chill and gives this recipe a creamy texture without chia seeds. You can use whole chia seeds instead if preferred.

Pumpkin pie spice - Adds the warm spices that give these pumpkin pie overnight oats their classic fall flavor. You can use ground cinnamon instead for a simpler flavor.

Vanilla extract - Adds a little extra flavor and complements the pumpkin and spices, but it can be omitted if needed.

Tips

• Give the oats time to soak - For the best texture, refrigerate overnight. They can be enjoyed after at least 3 hours, but the consistency will be thinner.
• Adjust the consistency - If the oats are thicker than you prefer, stir in a little more dairy-free milk before serving.
• Mix well - Make sure all of the oats are coated in the liquid so they soften evenly.

Topping ideas

These overnight oats with pumpkin are delicious on their own, or add your favorite toppings before serving. For meal prep, add crunchy toppings and fresh fruit right before eating for the best texture.

• Candied or toasted pecans or walnuts
• Dried cranberries
• Shelled pumpkin seeds
• Vegan chocolate chips
• Coconut yogurt 
• Oil-free granola
• Coconut whip
• Banana slices or berries

How to make pumpkin overnight oats

1. Combine the ingredients - Add all of the ingredients to a small bowl, jar with a lid, or airtight container. Stir well until everything is combined.
2. Chill - Cover and refrigerate for at least 3 hours, or preferably overnight, to allow the oats and ground flaxseed to absorb the liquid and thicken.
3. Stir and serve - Give the oats a good stir before serving. Add a splash of dairy-free milk if you prefer a thinner consistency, then add your favorite toppings.

Storage

Refrigerator - Store the overnight oats in an airtight container in the refrigerator for up to 5 days. For the best texture, enjoy them within 3 days. The oats will continue to soften and thicken as they sit.
