FAQs
Can I use instant oats or steel-cut oats?
You can, but instant oats may become too mushy, and steel-cut oats result in a chewy texture. Both need more soak time.
How long should I soak the oats?
For best results, soak overnight (about 8 hours). A minimum of 2 hours can work but yields a firmer texture.
Can I use yogurt instead of kefir?
Yes. Replace half or all of the plain kefir with Greek yogurt, though you may need less soaking time and a splash of milk for the right consistency.
Will this recipe work without chia seeds?
If you omit chia seeds, the oats might be slightly less thick. Consider adding extra oats or letting it soak longer for a hearty, chewy texture.
What’s the best ratio of oats to kefir?
A 1:2 ratio (½ cup oats to 1 cup kefir) creates the ideal creamy, not-too-thick base. Adjust to your desired consistency.
How do I make it vegan?
Use a dairy-free kefir (such as coconut, almond, or cashew-based), maple syrup, or agave as sweeteners, and skip any dairy add-ins.
Can I prepare it in the morning instead of overnight?
Yes. Let the oats and kefir sit for about 15 minutes for slight softening. You may need to stir more and use frozen fruit sparingly, since it won’t have time to defrost.
