Toasting a sub in the oven can be much easier than using a toaster, especially when you're using larger pieces of bread that don't fit in typical bread slots. You can either toast the bread in the oven first, then add toppings, or assemble the sandwich and toast it open-faced in the oven.
You can toast a sandwich in the oven by assembling it open-faced, like a tartine, and heating it on a baking sheet until the bread has some color and any hard cheese has melted. For sandwich in oven recipes, get creative with leftovers and fun combinations.
There are a few benefits to toasting a sub in the oven. It's a hands-off process, where all you have to do is preheat the oven, put in your baking sheet with the ingredients and then remove it when the time is up. You only have a sheet pan to wash, which you can do by putting it in the dishwasher, rather than cleaning a frying pan or panini press by hand.

Sandwich in Oven Recipes
A quick Internet search will yield plenty of sandwich in the oven recipe ideas. Preheat your oven to around 350 degrees Fahrenheit, then toast the bread on a sheet pan or directly on the baking racks. You can also assemble your two pieces of bread with the sandwich ingredients on top, like an open-faced tartine, and toast the entire thing using that method.
The sandwich is done when the bread begins to look golden brown, or any hard cheese has melted. This usually takes about 10 minutes, but keep an eye on your sandwich to ensure it does not burn in the oven.
Toasting a sandwich in the oven is a great way to use up leftovers, helping you reduce food waste — the Food and Drug Administration (FDA) estimates that we toss between 30 and 40 percent of our food. You can mix leftover grilled vegetables with goat's cheese, or try turkey and apples for a different flavor combination. A toasted PB&J makes for a fun twist on a classic sandwich.
Healthy Toasted Sandwiches
If you are following a certain meal plan or counting your macros, make sure to note down or weigh the ingredients in your sandwich for accurate nutritional information. There are plenty of swaps you can make to your favorite sandwich recipes for lower calories, increased protein or more whole grains instead of refined carbs.

Toasting a sub in the oven typically does not change the nutritional value of bread, though it can sometimes lower the glycemic index. If you're looking for a low-carb option, try toasting a sandwich in the oven made with cauliflower patties instead of bread.
To build a better sandwich, Harvard Health says, try to limit your use of processed meats — especially those that are high in sodium. Instead, load up on veggies and use flavorful cheeses, and get creative with nutritious spreads like hummus and avocado.
The NIH also recommends monitoring the amount of fat and sugar in your diet. The Cleveland Clinic explains that an adult's daily fat intake should be about 20 to 35 percent of their calories — so if you consume 2,000 calories per day, you should aim for somewhere between 44 grams and 77 grams of fat. Fat content in toasted sandwiches varies, but keep them in mind especially if you are cooking with butter or another high-fat food.
