    Substitutions

    Missing an ingredient? Don't worry, this frozen blueberry overnight oats recipe is easily customizable. Here are some suggestions:

    • Rolled Oats - instead of rolled oats you can use quick/instant oats. However, they will be soggy and won't have much texture. I don't recommend steel-cut oats for this recipe.
    • Almond milk - you can use oat milk, cashew milk, coconut milk, soy milk, or water.
    • Chia Seeds - replace chia seeds with flaxseed meal (ground flax seeds), hemp seeds, or pumpkin seeds (pepitas).
    • Peanut Butter - swap PB with Cashew Butter, almond butter, or coconut butter.
    • Maple Syrup - you can blend in 1-2 dates, agave nectar, or ½ banana in the blueberry milk to add natural sweetness.

    Variations

    This recipe is incredibly versatile here are some variations you can make:

    • Vegan Yogurt - you can add non-dairy yogurt to make it extra thick and creamy.
    • Protein Powder - for a boost of protein you can your favorite vegan-friendly protein powder.
    • Homemade Granola - stir in crispy granola for additional flavor and nutrition.
    • Nutty - mix in chopped hazelnuts, almonds, or walnuts for crunch and heart-healthy fats.

    Storage

    Your blueberry lemon overnight oats are great to make ahead and be stored for later. They will last for 4-5 days in an airtight container in the refrigerator.

    Top Tips

    • Use only plain rolled oats without added artificial flavors, colors, or sugar.
    • This recipe makes one serving, you can increase the ingredient quantities to make a large batch.
    • Omit the lemon zest if your lemon peel has a bitter taste.
    • Since the mixture is not too sweet, feel free to add an additional tablespoon of maple syrup or another sweetener of choice to make it suit your taste.
    • The best way to make the overnight oats is to let them soak overnight but if you are short on time you can soak them for at least 2 hours.

    FAQ

    What are overnight oats

    Overnight oats are oats that are left to soak in liquid (milk or water) in the fridge all night long. This simple nutritious meal doesn't require any cooking or heating up.

    How many hours is best for overnight oats

    The common question is what is the minimum time to soak overnight oats. Even though it is best to let the oats soak overnight, if you are in a rush, I recommend you wait for at least 2-3 hours to allow the oats fully soften and hydrate.

    How many calories are in blueberry overnight oats

    This cold satisfying meal contains 472 calories per serving.

    Can you eat overnight oats warm

    Of course, if you love eating your overnight oats warm simply heat them in the microwave or on the stovetop over medium heat until nicely warmed up and ready to eat. You may need to add more liquid to your oats mixture and constantly stir to prevent sticking.

    What is the best liquid for overnight oats

    Certainly, plant-based milk is the best liquid to make overnight oats. You can use any type of milk like almond milk, oat milk, cashew milk, or soy milk. Alternatively, soak rolled oats with other additions of choice in cold water. In addition, you can mix in some dairy-free yogurt or mashed banana for creaminess.

    Are 2 hours enough for overnight oats

    Although overnight oats are usually soaked overnight don't worry if you forget to prepare them the night before. They may not be as thick and velvety as overnight oats that have soaked longer but they are still delicious even if you soak them for at least 2 hours.

    Are overnight oats a good source of protein

    Absolutely! Rolled oats are an excellent source of quality plant protein if you are looking to boost your protein intake without meat or dairy. Also, they are rich in healthy carbs and essential nutrients like gut-filling soluble fiber (beta-glucan), manganese, copper, phosphorus, magnesium, and Vitamin B1.

    Can oats reduce belly fat

    Yes, oats can be an outstanding fat-burning superfood only if you combine them with diverse nutrient-dense foods to make a well-balanced meal. This low-calorie staple is highly beneficial for your overall health, especially for your gut and digestive tract. Because oats are packed with an abundance of fiber and natural protein, they can help you feel full for a longer period of time and will surely aid your flat belly and weight loss goals.
