If you prefer a tender and moist result, covered baking will be the better option. If you're desiring a crispy exterior and bolder flavors, uncovered baking is best.
The general rule is, if you want a browned or crisp surface, bake, or at least finish, the dish uncovered. If you want a soft or moist surface, cook the dish covered or foil-wrapped. When you do the latter, the food is actually steamed, rather than baked, which is the application of dry heat to food.
Covering the pot keeps steam from escaping, which can trap delicious aromas and reduce cooking time by allowing foods to steam. However, it is important to leave the lid off the pan during frying, searing, and deep-frying, as moisture interferes with creating a caramelized, crispy surface on these foods.

No lid. A lid defeats the purpose of the four incisions on the top. They exist to vent excess moisture from the filling. If you leave the lid on you will get a soggy crust because all of the moisture that is trying to escape gets trapped in the covered Dutch oven.

A covered baker can take many forms: From the Challenger bread pan to Dutch ovens to large pots, I've baked bread in many things. The key is that the vessel has a tight-fitting lid, which makes it excel at holding in moisture. For best results, be sure to preheat the vessel fully.
Covering a casserole helps the dish cook evenly, stay moist, and prevents burning. Uncovering helps with browning, crisping and allowing for steam to release.
Steaming foods like vegetables, tamales, seafood, and grains with the lid on supplies gentle, moist heat that will cook these foods to perfect tenderness without drying them out. "When you steam vegetables, you want the lid to trap the evaporating liquid in the pot, sealing the steam inside," says Welsh.
Reducing – if you're trying to thicken a sauce or soup, keep the lid in the cupboard. Evaporation is key in the reduction technique, so you want to allow that moisture to escape.
Generally, using aluminum foil in the oven is safe, offering efficient heat conduction and simplifying cleanup. More flexible and sturdy than tin foil, aluminum foil reflects heat and can typically tolerate the highest baking temperatures in most residential kitchen ovens, making it a great baking companion.
Lidded roasting pans excel at sealing in moisture and flavor during cooking, making them ideal for dishes that require a moist environment or longer cooking times. The lid helps to trap steam, which can result in more tender meats and vegetables.
“This steam helps to create moisture, allowing the vegetables to cook evenly and prevent them from drying out or sticking to the bottom of the kadhai. It also helps to infuse flavours and maintain the desired texture of the vegetables.
Should I cook my meatloaf covered or uncovered? The meatloaf can be cooked uncovered. However, if you are concerned about it burning, you can cover the meatloaf with foil for the first 45 minutes and uncover it for the final 15 minutes to allow the meatloaf to brown on top.
When using ovens with both fan-forced and conventional settings, it is best to use conventional when you are baking long and slow (like for cakes) and fan-forced for fast cooking at high temperatures. If using a fan-forced oven, as a general rule, drop the temperature by 20°C to imitate conventional.
Lining your oven with foil will actually increase the intensity of heat that will result in surface damage and even go as far as preventing even cooking. So leave it out, invest in an oven-safe cleaning cloth, and enjoy your golden brown cookies, holiday ham, and more!”
But when you put a lid on, the heat stays in the pot. It helps cook your food faster. Less time cooking results in less energy used. So yes, putting a lid on your pots and pans while cooking does make your food cook faster, saving energy.
Heat retention: A lid helps retain heat within the pan, which can be especially useful for dishes that require simmering or braising. It allows the food to cook evenly and retains moisture, resulting in tender and flavorful results.
Hair contamination and food safety
Even the most meticulous kitchen practices can fall short if proper precautions are not taken to prevent hair from contacting food. Chef hats & headwear act as a barrier, preventing loose hairs from falling into dishes and reducing the risk of contamination.
Covering foods prevents them from browning and crisping, but it does trap in moisture. Uncovering the foods promotes browning and crisping, and reduces the amount of liquid in the finished dish.
Generally, casseroles with grains, rice or pasta that will cook during the baking process are usually covered, for at least part of the time. Casseroles made of cooked ingredients are usually baked uncovered. If you like a crisper, browner top, be sure the casserole is uncovered for at least part of the bake time.
Covering a skillet, saucepan, or pot while cooking helps maintain temperature control, which is important for even cooking. It helps bring liquid to a boil faster, too (which uses less energy, aka, it's more cost efficient, too). Covering the pot keeps steam from escaping, too.
The short answer is both. Covering a casserole traps heat and steam and gets the casserole cooking. However, you also have to take the cover off to get a crunchy, browned top.
A Baking Sheet
It's a little bit bulkier than a regular pot lid, but it'll do the trick. It's an old test kitchen and restaurant secret for when the right-sized lid isn't available or doesn't exist.
The lid of the Dutch oven traps in the steam created from the liquid in the bread dough. It's the steam that gives you good oven spring and an airy crumb. Without it, the crust would harden too quickly and your bread would likely not expand to its full potential.
