10 Common Kitchen Mistakes You’re Probably Making (And How to Fix Them)

The kitchen is where the magic happens—until things go wrong. But don’t worry, you don’t have to make the same mistakes I did. I’ve learned some tough lessons along the way, and now I’m sharing the top 10 kitchen blunders to help you avoid kitchen chaos. Some of these might even make you laugh (looking back, I can’t help but chuckle), but each one comes with a valuable lesson for a safer, smoother cooking experience.

1. Don’t Drop Frozen Food Into Hot Oil

Why? The ice on frozen food reacts with hot oil, causing it to splatter and, in worst cases, catch fire.

It was my first weekend as a freshman in high school, and I was invited to my middle school friend’s start-of-year party at her newly renovated home. About 15 of us gathered for game night, and everything seemed perfect—until my two guy friends got hungry. They were tired of the candy and snacks, so they decided to heat up some hot dogs from the freezer on the frying pan. Suddenly, we noticed smoke filling the air—her brand-new kitchen was on fire. We quickly put out the flames, but the damage was done. The rest of the night was spent scrubbing dark scorch marks off the walls and counters. I didn’t stick around to see how the parents reacted the next morning, but I do know those two friends never got another invite to her house again.

2. Never Pour Water on a Grease Fire

Why? Water and hot oil don’t mix—at all.

Just like in that Friends episode where Rachel tried to fry a turkey for Thanksgiving, and things went wrong, she thought water would fix it. The fire flared up, and things went from bad to worse. While it's hilarious on TV, it’s a serious reminder in real life: Never pour water on a grease fire! Water causes the oil to splatter and spread, turning a manageable fire into a dangerous one. Instead, cover the fire with a lid, use baking soda to smother it, and—if it gets out of hand—grab a fire extinguisher.

3. Run Your Kitchen Disposal Regularly

Why? If you don’t, you risk a costly repair.

In my first apartment, I barely used the kitchen disposal, and after months of neglect, it ended up leaking. I had to call maintenance, only to find out the issue was much harder to fix than simply running the disposal once a month. Now, I make sure to run mine with ice, dish soap, and running water every month—even if I don’t use it much. It’s a quick, easy way to avoid expensive problems down the road.

4. Don't Use Metal Utensils on Non-Stick Pans

Why? You’ll ruin your non-stick pan and your food’s taste.

Your non-stick pan won’t stay non-stick for long, and you might end up with flecks of Teflon in your eggs.

Skip the Non-Stick Pans—Go for Cast Iron Instead! Non-stick pans may seem convenient because they’re easy to clean, but they come with potential health risks. Instead, consider investing in a cast-iron skillet. While it may cost more initially, it’s incredibly durable, long-lasting, and only improves with age. Plus, it imparts a rich, savory flavor to your food that non-stick pans can’t match. Stainless steel is another solid choice for its durability and excellent cooking performance, though it requires a bit more attention to prevent sticking. So, skip the non-stick and invest in high-quality cookware that will last longer and elevate your meals!

5. Keep Meat and Produce Separate

Why? Cross-contamination is a serious safety issue.

Keep meat away from produce and never use the same plate for raw and cooked meat. When preparing food, opt for wooden cutting boards, preferably pine or oak. Wood contains natural antimicrobial compounds that help inhibit the growth of harmful bacteria, whereas bacteria tend to survive longer on plastic boards.

6. Don't Drink Hot Water Straight from the Tap

Why? You’re drinking chemicals and bacteria—yuck!

I learned from my plumber that hot tap water can carry harmful chemicals from your pipes, and it's often not hot enough to kill bacteria. He even mentioned that he doesn't let his kids drink tap water—and he knows his stuff. To stay on the safe side, it's better to choose filtered water for things like tea or instant oatmeal.

In general, opting for mineral water over tap water is a smart investment in your health. It tastes better and contains beneficial minerals that tap water might lack. Though it costs a little more, the added health benefits—better hydration and supporting your body’s natural functions—make it worth the investment.

7. Never Store Hot Food in the Fridge

Why? It raises the fridge temperature, which can cause bacteria growth.

My college roommate once made a huge pot of soup for dinner. After eating some, she shoved the leftovers into the fridge while it was still hot. The next morning, I went to grab some strawberries, and when I opened the fridge door, I was hit with a strange smell. Turns out, the hot soup had raised the fridge temperature just enough to spoil some of our produce overnight. We had to toss it all. Lesson learned: always let your food cool down before sticking it in the fridge, or you’ll end up wasting more than just your meal.

8. Don’t Refreeze Thawed Food Without Cooking It First

Why? Bacteria love to grow on thawed food—cook it first to kill them off.

One time, I thawed frozen beef to stuff into gyoza wrappers, thinking I’d make them for a family visit later. But before I could cook them, I ended up popping them back into the freezer for later. When I finally cooked them, the gyoza didn’t look or taste right. The filling had a weird texture, and the flavor was off—definitely not the juicy, flavorful gyoza I had hoped for. It turns out thawing and refreezing can cause bacteria to multiply, and it ruins the texture and taste. I had to toss the whole batch. Lesson learned: always cook food before refreezing to keep it safe, fresh, and tasty!

9. Store raw chicken on the bottom shelf, followed by ground meat, then everything else on top.

Why? if anything leaks or drips, it falls onto foods that will be cooked at a higher temperature.

I once placed raw chicken on the middle shelf of the fridge. The chicken leaked. I had to throw out the greens, and the smell—ugh. Now, I store raw meat on the bottom shelf of my fridge, just in case. It’s simple, but it works.

10. Don’t Microwave Aluminum Foil (Unless You Really Know What You’re Doing)

Why? It can cause sparks and fires.

In most cases, aluminum foil and microwaves don’t mix. When foil is placed in the microwave, it reflects microwave energy, leading to arcing (sparks), which can damage your microwave and even cause a fire.

You may have seen instructions on certain pre-packaged foods that suggest using aluminum foil in the microwave. This is typically for specific purposes like distributing heat more evenly.

However, it’s better to transfer your meal to a plate, cover it with a microwave-safe cover, and stir occasionally. If you must use foil, keep it small, smooth, and ensure it doesn’t touch the microwave walls. Always follow the manufacturer’s instructions for safe use.

Final Thoughts

You can have a ton of fun in the kitchen, but let’s be honest—accidents happen even if when you’re careful. Follow these tips to keep things running smoothly (or at least less chaotically). And when things don’t go as planned, just laugh it off. Every “oops” is really just a funny story in the making.
