Cooking methods have evolved over time from traditional stovetop simmering and oven baking to modern techniques such as sous-vide and microwave steaming. A lesser-known, yet intriguing method involves using a dishwasher to cook foil-wrapped foods. This unusual cooking approach has garnered attention due to its ability to simultaneously clean dishes and cook a meal, saving both time and energy. But the question remains: Is it safe to cook food in your dishwasher? And if it is, what kinds of meals can be prepared in this unconventional appliance?
The Safety of Cooking in the Dishwasher
The first concern that comes to mind when considering cooking in a dishwasher is food safety. Thankfully, when food is securely wrapped in foil or placed in airtight glass jars, there is no risk of soap or other dishwasher chemicals contaminating the meal. The key aspect that ensures food safety when cooking in the dishwasher is temperature. Most dishwashers reach temperatures sufficient to cook certain foods to a safe internal temperature—this usually means reaching at least 140 degrees Fahrenheit for most dishes.

However, it is crucial to use a thermometer to check that the food has reached a safe temperature for consumption after the dishwasher cycle is complete. Another safety measure is to make sure that the food is completely sealed within the foil or jar to prevent water from entering and altering the texture or flavor of the meal.
1. Make certain that the seal is tight and secure to prevent any water or detergents from seeping in.
2. Always confirm that your dishwasher reaches the appropriate cooking temperatures and use a thermometer post-cycle to ensure food safety.
3. It's advisable to avoid cooking meats or other temperature-sensitive foods unless you're confident they can reach a safe temperature throughout.
4. Foods cooked in the dishwasher tend to poach in their own juices, so this method is not suitable for foods that require dry heat or crisping.
What Can You Make In Your Dishwasher?
The kinds of foods that are generally safe and suitable for dishwasher cooking are those that benefit from moist heat cooking methods, similar to poaching or steaming. Here's a list of foods that can be cooked in the dishwasher:
1. Vegetables: Root vegetables like beetroot, carrots, and potatoes can be seasoned, wrapped in foil, and placed in the dishwasher for a cycle to come out tender.
2. Fish: Delicate fish such as salmon can be seasoned with lemon, herbs, and olive oil, tightly wrapped in foil, and cooked through the gentle heat of the dishwasher.
3. Eggs: To hard-boil eggs, place them in a secure container or jar and run a normal to hot dishwasher cycle.
4. Fruits: Apples and pears can be cored, filled with cinnamon and sugar, wrapped in foil, and heated in the dishwasher for a soft, warm dessert.
5. Lasagna: Believe it or not, you can layer noodles, cheese, and sauce in a tightly-sealed, heat-proof container and cook it in the dishwasher.
Remember, not all dishwasher models are created equal, and cycle lengths and temperatures can vary widely. It's important to know your appliance's capabilities before experimenting with dishwasher cooking.

In conclusion, while cooking in a dishwasher might seem unconventional, it is indeed a safe and energy-efficient method provided that you strictly follow safety precautions to avoid contamination and ensure thorough cooking. Dishwasher cooking can be a fun and innovative way to prepare a limited range of dishes, especially when kitchen resources are sparse, or you're looking for a conversation starter at your next dinner party. However, it's not a replacement for traditional cooking methods, particularly for foods requiring high heat or a crisp exterior. So, if you're feeling adventurous and have some foil, airtight jars, and a bit of culinary curiosity, why not give dishwasher cooking a try? Just be sure to supplement this method with more conventional ones for the majority of your cooking needs.
