My Baked Overnight Oatmeal with Rhubarb and Almonds is an easy, make ahead recipe the whole family – sometimes even those who don’t like porridge – will love!
This recipe, adapted from another Baked Oatmeal Recipe from Oat & Sesame, was my gateway recipe to loving porridge. Now, after years of not liking porridge very much at all, now I can’t get enough! From Pear Walnut and Ginger Oatmeal to Gluten Free Cranberry Orange Baked Oatmeal, I’m always dreaming up yummy new recipes.
I particularly like the convenience of baked oatmeal recipes as they can be made the night before and kept in the fridge, ready to cook in the morning.
The Nutritional Benefits of Rhubarb and Almonds
There’s a lot more to rhubarb than meets the eye. Many people have only eaten it in pie, but it’s delicious in both sweet and savoury recipes. Rhubarb is also really good for you. Rhubarb contains fibre, calcium and could even help fight inflammation.
Almonds have health benefits as well. They are a prebiotic, so may be good for your gut biome. In addition to many other nutrients, they contain vitamin E, magnesium and protein.
Do Not Eat Rhubarb Leaves – Only Consume the Stalks
It is extremely important to note that rhubarb leaves are poisonous. The pretty pink stalks are perfectly safe, but never, ever eat the leaves. If you grow rhubarb or buy it with the leaves still attached, cut the leaves off and throw them away as soon as you can.
Baked Overnight Oatmeal with Rhubarb and Almonds
This recipe has all the great oat flavours I love in the fabulous texture of a moist, delicious, healthy cake. It’s really easy to throw together the night before and bakes up to golden deliciousness in the morning.
It’s the idea solution for people who love porridge – and especially for those who don’t.
Refined Sugar and Gluten Free with a Dairy Free Option
Baked Overnight Oatmeal with Rhubarb and Almonds is refined sugar-free and gluten-free. It can be made dairy-free by using your coconut or almond milk instead of cow’s milk and using oil to grease the pan instead of butter.
How To Serve
Baked Overnight Oatmeal with Rhubarb and Almonds is delicious served just as it is but it tastes especially nice with a drizzle of yogurt, or even some cream if you are feeling indulgent.
I also love to serve this recipe with some strawberries on the side. Strawberry and rhubarb make a wonderful flavour partnership.
Baked Overnight Oatmeal Keeps Beautifully
If you do have any leftovers they will keep well for a couple of days, and reheat beautifully in the oven or microwave. If we are just the two or three of us at home on Sunday, I like serve the leftovers for a super easy breakfast Monday morning. It really starts the week off right.
