Smarter Cooking: Simple Swaps to Save Energy in the Kitchen
We don’t always think about energy use when we’re chopping onions or boiling pasta. But the way we cook can have a real impact—not just on our bills, but on the environment, too. The good news is that small changes go a long way. By rethinking how we prep, cook, and heat our food, we can save energy without sacrificing flavor or convenience.
It all starts with thinking small—literally. Downsizing your ingredients can make a big difference. Smaller items cook faster, which means less energy used overall. So instead of going for the giant baking potatoes, try two medium ones per person. Switch out large chunks of veg for smaller dice, and use mini chicken fillets instead of whole breasts. Even pasta shapes matter—tiny options like orzo cook much quicker than their larger counterparts. Just remember to check if the smaller versions cost more per kilo. If they do, buy big and cut them down at home.
When it comes to cooking methods, the oven isn’t always your best friend. Grilling can achieve the same golden finish in a fraction of the time. You don’t need to bake a casserole for 45 minutes just to get a crusty top—heat it through in the microwave, then pop it under the grill for a few minutes. Many vegetables that we usually roast—like zucchini or peppers—do beautifully under the grill as well. And spatchcocking a chicken makes it ideal for grilling, cutting both time and energy use. Just be sure to use only as much of the grill’s surface as you need.
Water and cookware choices matter more than you’d think. Always pick the smallest saucepan that will do the job, and use only as much water as needed. A tightly fitting lid keeps the heat in, helping food cook faster at lower temperatures. Green vegetables need just a little bit of water and only a few minutes on the heat. Even pasta, long treated as a water-hungry dish, doesn’t need to swim in a vat. Just give it room to move and a bit of stirring, and you’re set. Bonus: that starchy water is perfect for emulsifying sauces.
One of the biggest game-changers in energy-efficient cooking? The air fryer. It’s not just a trend—it’s a serious contender when it comes to cutting oven time and energy use. Whether you’re crisping fries, roasting a handful of tomatoes, or warming a pie, the air fryer gets the job done faster, more efficiently, and with barely any oil. Most models bake, grill, and reheat as well, making them far more versatile than people give them credit for. And they clean up easily, which never hurts.
Here’s another simple shift: don’t cook from frozen. It can take twice as long (and twice the energy) to reheat something straight from the freezer. Unless the packaging says otherwise, take it out the night before and let it thaw in the fridge. It’ll reheat faster and more evenly, saving time and power.
If you really want to supercharge your efficiency, it might be time to rediscover the pressure cooker. These powerful pots are making a big comeback, and for good reason. They turn tough cuts into tender stews in under 40 minutes, and modern electric versions even handle the timing and pressure for you. The higher-end models can do everything from slow cooking and rice steaming to yogurt-making and air frying—making them a true kitchen workhorse.
Looking for even more ways to trim your energy use? Here are a few bonus tips:
- Steep, don’t simmer: Soak rice noodles, choose couscous over traditional rice, and let meats cook in residual heat after boiling.
- Soak before you cook: Beans, lentils, and grains all cook faster if they’ve had a good soak first.
- Embrace the microwave: It’s not just for leftovers. Use it to cook vegetables, fish fillets, even quick mug cakes.
- Skip the peeling: Roast root veg and squash with the skins on—they’re edible and full of nutrients.
- Skip the preheat: Unless you’re baking something delicate, just put your food in the oven while it’s warming up.
At the end of the day, saving energy in the kitchen doesn’t mean changing everything—it’s about being a little more intentional with what we cook, how we cook it, and the tools we use. Small tweaks, big impact. And often, quicker dinners, too.
