How to Make Oatmeal

By ShowMeStepByStepPublished Updated

Based on a video by Feelgoodfoodie.

Oatmeal is the most reliable cheap breakfast there is. The 2:1 water-to-oats ratio works for any quantity, and stovetop or microwave both come out the same. The only real choice is texture (rolled oats hold up; instant turns to paste) and toppings.

Common questions

What's the water-to-oats ratio for oatmeal?

Two to one. That's half a cup of rolled oats to one cup of water for a single microwave bowl, or 6 cups water to 3 cups oats for a stovetop family batch.

Can I make oatmeal with water instead of milk?

Yes, water works perfectly and keeps it light. Milk makes it creamier and richer, and half water plus half milk is a nice middle ground.

How do I store and reheat meal-prep oatmeal?

Scoop the cooked batch into sealed containers and refrigerate up to 5 days. Reheat each morning in the microwave with a splash of water or milk to loosen it back up.

Step-by-Step Guide

1

Use Rolled Oats

0:10
Step 1: Use Rolled Oats

Grab a jar of rolled oats (also labeled old-fashioned oats). They're whole oats that have been steamed and flattened - minimally processed, hold their texture, and give you a creamy bowl that doesn't turn to paste. Skip instant oats; they cook to mush.

Tip

Steel-cut oats work too but take 25-30 minutes. For the same speed and a similar mouth-feel, rolled is the best default.

Microwave Method - One Bowl

0:50
Step 2: Microwave Method - One Bowl

Measure 1/2 cup rolled oats into a microwave-safe bowl. Add 1 cup water and a small pinch of salt. The 2:1 water-to-oats ratio is the rule - it works at any scale.

3

Microwave 2 Minutes

1:15
Step 3: Microwave 2 Minutes

Microwave on high for 2 minutes. The oats absorb the water, soften, and turn creamy. Stir before eating since the bottom is sometimes drier than the top.

Tip

If your microwave runs weak, add 30 seconds. If it boils over, try 90 seconds in a deeper bowl.

Stovetop Method - Family Size

2:10
Step 4: Stovetop Method - Family Size

For 4-8 servings or weekly meal prep: bring 6 cups of water to a boil in a large pot. Add 3 cups of rolled oats and about 1/2 teaspoon of salt. Salt isn't optional - it brings out the natural sweetness of the oats and rounds out the flavor.

5

Stir 5 Minutes Until Thick

2:50
Step 5: Stir 5 Minutes Until Thick

Stir occasionally for about 5 minutes until the water is absorbed and the oats are thick and creamy. The texture should hold a soft mound on a spoon - not soupy, not paste. Use this time to chop fruit or measure out toppings.

6

Cover and Rest

Step 6: Cover and Rest

Turn off the heat, cover the pot with a lid, and let it sit for 2 minutes. Residual heat finishes the cook and the texture evens out. This step is what separates good oatmeal from great oatmeal.

Top and Serve

Step 7: Top and Serve

Four topping combos that beat the packets:

  • Maple brown sugar - maple syrup, brown sugar, a shake of cinnamon
  • Banana nut - sliced banana, chopped walnuts, drizzle of honey
  • Strawberries and cream - sliced strawberries, splash of cream, drop of vanilla
  • Chocolate peanut butter - chocolate chips, spoon of peanut butter, banana coins on top

Meal Prep for the Week

Step 8: Meal Prep for the Week

Scoop the cooked stovetop batch into 4-8 sealed containers and refrigerate. They keep for 5 days. Reheat each morning in the microwave with a splash of milk or water to loosen the texture - cold-stored oatmeal tightens up and needs the liquid back.
