Recipe Details

Prep time: 10 minutes | Cook time: 0 minutes | Total time: 8 hours 10 minutes | Yield: 1 serving | Category: Breakfast | Cuisine: American

Ingredients

Original recipe (1×) yields 4 servings

  • 1/2 cup old-fashioned rolled oats
  • 1 tablespoon ground flaxseed (flax meal)
  • 1/3 cup pumpkin purée (not pumpkin pie filling)
  • 2/3 cup unsweetened soy milk
  • 1/2 teaspoon ground cinnamon
  • 1/8 teaspoon ground ginger
  • Pinch of freshly grated nutmeg
  • 1 teaspoon maple syrup, optional

Tips for Pumpkin Spice Flax Overnight Oats

First, use old-fashioned rolled oats for the best texture. Quick oats will get softer, and steel-cut oats need longer soak time. Next, measure the flaxseed by tablespoon. Additionally, choose unsweetened plant milk to keep added sugars low. For a touch of sweetness, add maple syrup or a mashed banana. Finally, use a 12-ounce jar or bowl for easy mixing.

Instructions

  1. Stir every ingredient together in a jar until evenly combined. If you prefer thinner oats, add an extra tablespoon of milk now.
  2. Cover and refrigerate for at least 6 hours or overnight so the oats and flax can absorb the liquid.
  3. Stir before serving and add a splash of milk if needed. Top with chopped nuts, seeds, or extra pumpkin purée for more texture.

Why This Breakfast Works

This recipe pairs whole-grain oats with ground flaxseed and pumpkin purée for fiber and texture. The flaxseed adds plant-based omega-3 fats, while pumpkin contributes vitamin-rich color and natural sweetness. In addition, using soy milk keeps this bowl plant-forward and higher in protein than many other plant milks. For more simple breakfast ideas, visit The Nutrient.

Substitutions and Variations

  • Milk: Replace soy milk with oat, almond, or cashew milk. If you use dairy milk, choose lower-fat milk and be aware it changes the recipe's profile; however, plant milk keeps it plant-forward.
  • Sweetener: Swap maple syrup for honey or mashed ripe banana.
  • Spices: Add 1/4 teaspoon pumpkin pie spice instead of the cinnamon and ginger mix.
  • Boosts: Stir in 1 tablespoon chia seeds for extra gel-like texture, or add 2 tablespoons plain Greek yogurt for creaminess (note: yogurt adds dairy).

Save Time

  • Prepare the make-ahead components earlier and refrigerate them until cooking or serving.

Storage

Refrigerate covered for up to 3 days. Stir well before eating. For travel, keep chilled in a sealed jar and consume within 24 hours if not refrigerated constantly.
