Once we discovered cooking oat groats in the Instant Pot, we haven’t turned back!

What Are Oat Groats?

Oat groats are the whole, unprocessed oat kernel with only the outer hull removed. Unlike rolled oats or steel-cut oats, which are further processed for quicker cooking, oat groats are the most intact form of oats. They have a chewy texture similar to barley or farro, with a mild, nutty flavor that’s incredibly versatile. Think of them as the “whole grain” version of oats—perfect for savory pilafs, salads, or creamy porridges.

Where to Purchase Oat Groats

Now, let’s get to the recipe. This makes about 4 servings as a side or base for bowls, and it’s super easy to scale up.

Alternative Cooking Methods

No Instant Pot? You can also easily cook oat groats in a saucepan on the stove! The ingredients remain the same.

Stovetop Method:

Rinse the Groats: Rinse under cold water as above.
Boil the Liquid: In a medium saucepan, bring 3 cups of water or broth to a boil over high heat. Add a pinch of salt if desired.
Add Groats and Simmer: Stir in the rinsed oat groats, reduce heat to low, cover, and simmer for 45-50 minutes, stirring occasionally. Check for doneness—they should be tender but still chewy.
Rest and Drain: Remove from heat and let sit covered for 5-10 minutes. Drain any excess liquid.

Total time: About 55-60 minutes

Slow Cooker:

Use a 1:3 ratio of groats to liquid and cook on low for 6-8 hours or high for 3-4 hours. Check for doneness and drain excess liquid if needed.

Rice Cooker:

Oat groats can also easily be cooked in a rice cooker following the manufacturer’s instructions for cooking brown rice.

Tips and Variations

Meal Prep Magic: Cooked oat groats store beautifully in the fridge for up to 5 days or freeze for 2-3 months. Reheat with a splash of water.
Adjust Liquid for Texture: The 1:2 groats-to-liquid ratio works best for a firmer pilaf-style texture, but adjust slightly if you prefer a creamier texture. A 1:3 ration produces a creamier porridge.
Pro Tip: Soak the groats overnight to reduce cooking time by about 10 minutes and improve digestibility.

Recipe Success Tips

Check for Freshness: Ensure your oat groats are fresh by purchasing from a store with high turnover or checking the expiration date. Stale groats can taste off and take longer to cook.
Stir Minimally on Stovetop: Over-stirring during stovetop cooking can make the groats gummy. Stir just enough to prevent sticking.
Cool Before Storing: Let cooked groats cool slightly before transferring to airtight containers to prevent condensation and sogginess in the fridge.

Variations

Sweet Breakfast Bowl: Stir in milk, maple syrup, fresh berries, sliced almonds, or a dash of vanilla extract after cooking for a cozy breakfast. We also love to use butter, maple syrup, ground cinnamon, pistachios, and raisins for a breakfast bowl.
Savory Grain Bowl: Use vegetable or chicken broth instead of water, and mix in sautéed mushrooms, spinach, fresh herbs, or grilled chicken for a hearty meal.
Meal Prep Friendly: Cooked oat groats store well in the fridge for up to 5 days or in the freezer for 2-3 months. Reheat with a splash of water or broth to restore texture.
Overnight Soak Option: Soak groats overnight in water to reduce cooking time by about 10 minutes and enhance digestibility, especially for sensitive stomachs.

Oat groats are whole oat kernels with only the hull removed, making them the least processed. Steel-cut oats are groats chopped into smaller pieces, and rolled oats are steamed and flattened groats. Groats take longer to cook but offer a chewier texture and more intact nutrients.

Absolutely! Their chewy texture makes them a great substitute in grain bowls, pilafs, or salads. We also enjoy them as a side dish in place of rice or quinoa. Just adjust cooking times and liquid ratios as needed.

Yes, oat groats are naturally gluten-free. However, if you have celiac disease or gluten sensitivity, choose certified gluten-free oat groats to avoid cross-contamination during processing.

Store cooled oat groats in an airtight container in the fridge for up to 5 days or freeze for up to 3 months. Reheat with a splash of liquid to restore texture.

Mushiness can result from overcooking or too much liquid. Stick to the 1:2 ratio for a chewier texture, and check doneness early to avoid overcooking.
