Pumpkin Pie Overnight Oats with Toasted Pumpkin Seeds

Stir the breakfast together tonight and let the refrigerator do the softening. Pumpkin purée gives these oats a mellow autumn flavor; cinnamon, ginger and nutmeg supply the pie-like warmth without needing pie filling. Toasted pumpkin seeds added just before eating keep their crunch.

Recipe development note: this original, researched recipe has not been kitchen-tested. Oat brands and pumpkin purées vary; use the texture adjustments below.

Recipe at a glance

• Yield: 2 breakfast portions
• Active time: about 10 minutes, including toasting the seeds
• Chill: at least 8 hours, overnight
• Total: about 8 hours 10 minutes
• Equipment: mixing bowl, spoon, small skillet and two covered 12–16 fl oz (350–475 ml) containers

Ingredients

US measures are used; metric amounts are rounded. Choose plain pumpkin purée, not sweetened pumpkin pie filling.

• 1 cup (80 g) old-fashioned rolled oats suitable for overnight soaking; not steel-cut oats
• 1 cup (240 ml) unsweetened soy milk, plus up to ¼ cup (60 ml) to loosen after chilling
• ½ cup (120 g) canned plain pumpkin purée
• 1 tablespoon (12 g) chia seeds
• 1 tablespoon (15 ml / 20 g) pure maple syrup, plus more to taste
• ½ teaspoon (2.5 ml) vanilla extract
• ½ teaspoon (1 g) ground cinnamon
• ¼ teaspoon (0.5 g) ground ginger
• ⅛ teaspoon (0.25 g) ground nutmeg
• Small pinch of fine salt, about 1/16 teaspoon (0.4 g)
• 2 tablespoons (16 g) unsalted hulled pumpkin seeds, also called pepitas

Method

1. Mix the pumpkin base. In a bowl, stir the measured soy milk, pumpkin purée, maple syrup, vanilla, cinnamon, ginger, nutmeg and salt until the pumpkin is evenly dispersed. Scrape any lumps against the side of the bowl.
2. Add the oats and chia. Stir in the rolled oats and chia seeds thoroughly, scraping the bottom. Let stand for 5 minutes, then stir again to break up any chia clumps. Divide evenly between two clean containers and cover.
3. Chill, not counter-soak. Put the covered containers straight into a refrigerator at 40°F (4°C) or below for at least 8 hours. The oats should become soft and the mixture thick and spoonable; this is a cold-soaked breakfast, not a stovetop porridge.
4. Toast the topping. While preparing the jars, place the pumpkin seeds in a dry small skillet over medium-low heat. Stir frequently for about 3–5 minutes, until fragrant, lightly golden in places and beginning to pop. Remove promptly to a plate so they do not burn. Cool fully and keep in a separate airtight container until serving. If using already-roasted unsalted pepitas, skip the skillet.
5. Adjust and serve. Stir each chilled portion. If it is too thick, add extra soy milk 1 tablespoon (15 ml) at a time, up to 2 tablespoons (30 ml) per portion. Taste and add a little more maple syrup only if wanted. Scatter half the toasted seeds over each portion just before eating; serve cold.

Make it work with your cupboard

• Milk: replace soy milk with the same amount of unsweetened oat or almond milk. Choose a plant milk you already enjoy; almond milk introduces a tree-nut allergen. Use a clearly soy-free milk if avoiding soy.
• Oats: old-fashioned rolled oats keep some texture. Quick oats become softer; steel-cut oats are not a direct substitute for this cold-soaking method. Follow any instruction on your oat package requiring cooking. For a gluten-free version, use certified gluten-free oats and check all other labels.
• Spices: replace the cinnamon, ginger and nutmeg with ¾ teaspoon (about 1.5 g) pumpkin pie spice if that is already in your cupboard. Check the blend for unwanted added ingredients.
• Sweetener: use agave syrup in the same volume instead of maple. Avoid honey for a vegan breakfast. Sweetened plant milk may need less added syrup.
• Topping: sunflower seeds can replace pepitas in the same amount. Keep the topping separate until serving rather than letting it soften overnight.

Budget and make-ahead tips

Store-brand rolled oats and canned pumpkin work here; you do not need individual flavored oat packets. Compare unit prices for seeds, and buy the smaller package if a large bag would go unused. Portion leftover pumpkin purée into small freezer-safe containers, label and freeze promptly for a future batch; thaw in the refrigerator and stir before measuring.

Make these two portions the evening before breakfast and eat within 24 hours for the best texture. For a longer head start, measure dry oats and spices into containers, then add the wet ingredients and chia the night before you need them. Keep plant milk and opened pumpkin refrigerated according to their labels; mixing them into oats does not extend their storage life.

Storage and small fixes

Keep the covered jars refrigerated at 40°F (4°C) or below, including while the oats soften. Use clean utensils, and do not leave the prepared oats out for more than 2 hours, or 1 hour above 90°F (32°C). If taking a jar to work, use an insulated bag with ice packs and refrigerate on arrival. Do not rely on smell alone to judge food safety.

Too stiff? Stir in the measured extra milk gradually. A little loose? Stir well and allow another hour in the refrigerator; chia and oats need time to absorb liquid. Bland? Taste after chilling before adjusting sweetness or spice. A purée that is unusually watery will give a looser result than thick canned pumpkin.
