Fresh spring peas blitzed into your overnight oats sounds like a dare, but this Thai-inflected breakfast is genuinely, aggressively delicious. The natural sweetness of peas mirrors coconut milk's richness, while cardamom and lime zest do exactly what lemongrass and makrut lime do in a Thai dessert — cut fat, lift earthiness, and make everything smell like a fever dream in the best way. Science said yes, your skeptical brain just needs to catch up.
Ingredients
- 1 cup gluten-free rolled oats
- 200g fresh or thawed frozen spring peas
- 1 cup full-fat coconut milk, well shaken
- 0.5 cup cold water
- 2 tablespoons chia seeds
- 1.5 tablespoons maple syrup, plus more to taste
- 0.75 teaspoon ground cardamom
- 0.5 teaspoon ground turmeric, for color depth
- 1 lime, zested and juiced (about 2 tablespoons juice)
- 0.25 teaspoon fine sea salt
- 0.5 teaspoon pure vanilla extract
- 2 tablespoons unsweetened desiccated coconut, toasted, for topping
- 2 tablespoons roasted salted peanuts, roughly chopped, for topping
- 1 tablespoon fresh mint leaves, torn, for topping
- 0.5 teaspoon black sesame seeds, for topping
- 1 small lime, cut into wedges, for serving
- extra fresh peas, for garnish
Instructions
1. Blend the peas: Add the spring peas, coconut milk, and cold water to a blender. Blitz on high for 60–90 seconds until completely smooth and vividly green. Don't shortcut this — you want a silky liquid, not a chunky situation. Taste it. It should be sweet, grassy, and a little oceanic from the coconut.
2. Season the base: Add the maple syrup, cardamom, turmeric, lime juice, lime zest, salt, and vanilla extract to the blender. Pulse 3–4 times to combine. Taste again and adjust — more lime if it needs brightness, more maple if the peas are on the starchy side.
3. Combine with oats and chia: In a large mixing bowl or directly into two wide-mouth jars, combine the rolled oats and chia seeds. Pour the green pea coconut mixture over the oats and stir vigorously for 30 seconds to prevent chia clumping. The color will be an alarming jade green. This is correct. This is the goal.
4. Rest and set: Divide evenly between two jars or bowls if you haven't already. Stir once more, then press a piece of plastic wrap or a lid directly onto the surface. Refrigerate for a minimum of 8 hours, ideally overnight. The chia seeds will absorb liquid and create a pudding-like texture while the oats soften.
5. Morning check: Pull from the fridge. The mixture should be thick, creamy, and spoonable — a deep, matte green. If it's thicker than you like, stir in a splash of coconut milk or water to loosen. Taste and add a tiny extra squeeze of lime or pinch of salt if needed.
6. Top and serve: Spoon into bowls or eat straight from the jar. Top with toasted desiccated coconut, chopped peanuts, torn mint, black sesame seeds, and a handful of fresh peas scattered on top. Serve with lime wedges on the side for extra brightness at the table. Eat immediately while the toppings still have crunch.
Why It Actually Works
Spring peas are naturally high in sugars and glutamates, which means they contribute both sweetness and a mild savory depth that makes the coconut milk taste richer and more complex — the same reason peas work so well in Southeast Asian coconut desserts like Thai lod chong. Cardamom shares key aromatic compounds (terpineol, linalool) with makrut lime leaf, so it bridges the Thai flavor logic without requiring specialty ingredients, while the lime juice's acidity cuts through coconut fat and brightens the grassy chlorophyll notes of the peas rather than clashing with them. Chia seeds and oats both absorb liquid overnight through starch gelatinization and mucilage swelling respectively, locking the green pea coconut base into a stable, creamy matrix that doesn't separate or oxidize significantly because the lime juice acts as a mild antioxidant.
Variations
- Swap cardamom for a pinch of Thai green curry paste whisked into the blend — it adds galangal and lemongrass notes that push the Thai identity even harder, with a subtle savory warmth that will confuse and delight everyone at your breakfast table.
- Add 2 tablespoons of spirulina powder to the pea blend for a double-green protein boost and a color so aggressively emerald it looks like a special effect — the coconut milk keeps it from tasting like a pond.
- Make it a dessert-for-breakfast situation by topping with mango cubes and a drizzle of coconut cream — the tropical sweetness plays off the grassy pea base exactly like mango sticky rice plays off coconut, because flavor logic is universal.

More Strange Recipes

Fermented Oat and Anchovy Congee with Crispy Shallots
Imagine if a Nordic fisherman and a Cantonese grandmother got snowed in together and decided breakfast was the hill they'd die on — this is that bowl. Lacto-fermented rolled oats break down into a silky, porridge-like congee base with a gentle tang that makes the briny, glutamate-rich anchovies sing rather than shout. The crispy shallots and spring onion cut through the richness with textural drama, delivering a breakfast that is simultaneously ancient, weird, and deeply correct.

Morel Dutch Baby with Truffle Butter and Ramp Confiture
A custardy, oven-puffed Dutch baby — already a theatrical breakfast anomaly — gets hijacked by the French spring forest: earthy morel mushrooms folded into the batter, a glossy truffle butter melted over the hot skillet edge, and a jammy ramp confiture that brings wild-onion sweetness to every forkful. It sounds like a fine-dining tasting menu crashed your Sunday brunch, and that is exactly the point. The science of high-heat steam lift meets the umami triumvirate of morel, truffle, and allium in a single cast-iron moment.

Asparagus & Feta Shakshuka with Wild Garlic and Morel Mushrooms
Shakshuka gets a verdant spring makeover when tender asparagus spears, earthy morel mushrooms, and pungent wild garlic crash the traditional tomato-and-egg party alongside crumbled feta. Steaming the eggs low and slow over the saucy vegetable base keeps the whites silky rather than rubbery while the yolks stay gloriously jammy — a trick borrowed from Moroccan tagine technique. The combination sounds like a farmers'-market fever dream, but the umami depth of morals, the grassy brightness of wild garlic, and the briny funk of feta create a flavor scaffold that makes perfect sense.
