Oats: A Comprehensive Guide
1. History of Oats:
Oats (Avena sativa) boast a fascinating history, dating back to ancient times. They are believed to have originated in the Fertile Crescent and were initially cultivated as a weed amongst wheat and barley crops. Over time, oats gained prominence, especially in colder climates unsuitable for other grains. In ancient Rome, oats were primarily used to feed livestock. However, in regions like Scotland and Scandinavia, they became a dietary staple, forming the base for porridge, a hearty and sustaining meal. Historically, oats were also used in various folk remedies, highlighting their perceived health benefits.
2. Cooking Techniques:
Oats are incredibly versatile. Here's a breakdown of how to cook them:
How to cook oats (general overview):
The most common method is to cook oats on the stovetop or in a microwave with water or milk. The ratio varies depending on the type of oats. For rolled oats, a general guideline is 1 part oats to 2 parts liquid. For steel-cut oats, use a 1:3 or 1:4 ratio. Bring the liquid to a boil, add the oats, reduce the heat and simmer, stirring occasionally, until the oats reach your desired consistency. Microwave instructions are typically printed on the oat packaging.
How to prepare oats for cooking:
No special preparation is needed before cooking most types of oats. Rolled oats and quick oats can be added directly to the liquid. Steel-cut oats may benefit from a brief rinse under cold water to remove any dust or debris. Instant oats are pre-cooked and can simply be mixed with hot liquid.
How to grill oats:
While less common, oats can be grilled for added texture and flavour. This is best done with pre-cooked or par-cooked oats. You could for example prepare oatcakes and grill them. Lightly brush cooked oatcakes with oil and grill until lightly toasted, turning once. This will give it a slightly charred, smoky taste.
How to bake oats:
Oats are excellent in baked goods. They add a chewy texture and nutty flavour to muffins, cookies, flapjacks, and crumbles. Oats can be added directly to the dry ingredients. You can also make baked oatmeal by combining oats with milk, eggs, fruit, and sweeteners, and then baking it in the oven.
How to sauté oats:
Sautéing oats can create a lovely nutty flavour. Heat oil or butter in a pan over medium heat. Add oats and sauté, stirring frequently, until they turn golden brown and fragrant. This technique is often used to prepare savoury oat dishes or to add extra flavour to granola.
3. Ingredient Preparation:
As oats are usually used whole or cut, there is no need for further cutting, peeling, dicing or mincing.
4. Storage:
How to store oats (short-term and long-term):
Store oats in an airtight container in a cool, dry place, away from direct sunlight and moisture. This will maintain their freshness and prevent them from absorbing odours. For short-term storage, the pantry is suitable. For long-term storage, consider the fridge or freezer, especially for large quantities.
How long does oats typically last under different storage conditions?
- Pantry: Rolled oats and quick oats can last for 6-12 months. Steel-cut oats can last for 1-2 years.
- Fridge: Oats can be stored in the fridge for 6-12 months, extending shelf life.
- Freezer: Oats can be frozen for up to 2 years, preserving their quality and extending their use.
5. Substitutions:
What are good substitutes for oats?
- For those with allergies or seeking variety: Quinoa, barley, or brown rice can be used in similar applications like porridge or as a base for savoury dishes. Rice flakes can also be used.
- For texture: Chia seeds, flaxseed meal, or even ground nuts can mimic the texture of oats in some recipes.
6. Nutritional Information:
Oats nutrition facts:
Oats are a nutritional powerhouse. They are rich in:
- Fibre: Especially soluble fibre, which is beneficial for heart health and helps regulate blood sugar levels.
- Complex carbohydrates: Providing sustained energy.
- Protein: A moderate amount of protein.
- Vitamins and Minerals: Including B vitamins, iron, magnesium, and zinc.
Key health benefits of consuming oats:
- Heart Health: The soluble fibre in oats, beta-glucan, can help lower LDL (bad) cholesterol levels. This is a huge plus.
- Blood Sugar Control: Oats have a low glycaemic index (GI), meaning they release sugar slowly into the bloodstream. This is beneficial for managing blood sugar levels, especially for people with diabetes or insulin resistance.
- Digestive Health: The fibre content promotes regularity and can help prevent constipation.
- Weight Management: Oats can promote satiety, helping you feel full and satisfied for longer, which may aid in weight management.
7. Pairing:
What flavors and ingredients go well with oats?
Oats pair beautifully with a wide range of flavours:
- Fruits: Berries, bananas, apples, and dried fruits (raisins, cranberries) complement oats perfectly.
- Nuts and Seeds: Almonds, walnuts, pecans, sunflower seeds, and pumpkin seeds add crunch and healthy fats.
- Spices: Cinnamon, nutmeg, ginger, and cardamom enhance the flavour profile.
- Sweeteners: Honey, maple syrup, brown sugar, or stevia can be used to sweeten oats. Consider natural sweeteners to improve your health.
- Savoury additions: Consider adding herbs such as thyme, sage, or rosemary, or spices like paprika to savoury oat dishes, or even cheese and vegetables.
8. Cleaning and Washing:
How to wash oats properly:
Most commercially available oats are cleaned during processing. It's generally not necessary to wash oats before cooking. However, if you're using oats from a bulk bin or if you prefer, you can give them a quick rinse in a fine-mesh sieve under cold running water. Be careful not to over-rinse, as this could potentially wash away some of the nutrients. After washing, simply drain the oats well before using.
9. Ripeness:
Not applicable for Oats. Oats are a dried grain and don’t ripen in the same sense as fruits.

FAQs
Naturally, oats are gluten-free. However, they are often processed in facilities that also process gluten-containing grains, leading to cross-contamination. If you have coeliac disease or a severe gluten intolerance, look for oats certified as gluten-free.
Which type of oats is best for weight loss?All types of oats can contribute to weight loss due to their high fibre content, which promotes satiety. However, steel-cut oats and rolled oats tend to be less processed and may have a slightly lower GI than instant oats, making them a good choice.
Can I eat raw oats?Yes, you can eat raw oats, but they are generally not as easily digestible as cooked oats. Raw oats can be added to smoothies, granola, or overnight oats. Soaking them in liquid (water, milk, or yoghurt) overnight can help soften them and make them easier to digest.
What are overnight oats?Overnight oats are a no-cook method of preparing oats. Oats are combined with a liquid (milk, water, or yoghurt) and other desired ingredients (fruit, nuts, seeds, sweeteners) and refrigerated overnight. This allows the oats to soften and absorb the liquid, creating a creamy and convenient breakfast.
Can I use oats in skincare?Yes, oats have been used in skincare for centuries. Finely ground oats (oatmeal) can be used as a soothing and gentle cleanser for sensitive skin, relieving dryness and irritation. They are also a key ingredient in some skincare products.
