Who says sheet pan dinners can't be a little saucy?

Probably the biggest complaint I've heard about sheet pan dinners (and had through my own experience cooking them) was that the meal turned out dry. And, of course that's a possibility - you're literally roasting the moisture out of your meal! But, as it turns out, it's super easy to combat that.

I've found that, if you roast the solid ingredients down to really concentrate their flavor and add in any wet ingredients after cooking, you can capture the best of both worlds. That's exactly what I did with this Sheet Pan Meatball & Pepper Subs recipe. You simply roast the veggies and meatballs in the oven and add in your sauce at the very end to get a super flavorful, savory, but not over-dry sub filling that's incredibly tasty.

This one was super easy to throw together for the freezer. You simply have to chop up a few veggies and assemble - really no meat prep needed! The flavors are so rich when you roast this too - this is definitely the way to go when prepping any kind of peppers, onions, or even tomatoes.

Here's how this sheet pan dinners series works...

A few summers ago, I shared a collection of sheet pan meals. The week after I share the last one, I posted a full set of sheet pan meals with all of these meals and more - prep them all in one day for weeks of easy dinners!

A few simple tips...

• Aluminum foil is your friend! I line my cookie sheets in aluminum foil before putting the meal on to cook each time. Makes clean-up a breeze. I also recommend lightly spraying your aluminum foil with a non-stick spray before adding the meal.
• Aluminum foil is also helpful to guard against drips in your oven. Most of these frozen meals will be melting off a good bit of condensation when cooking - that can sometimes make for a messy oven (and lots of smoke). To prevent this, use a baking sheet with a ½-1" lip around the edge. If you don't have that, fold the edges of your aluminum foil up to make a lip - that helps!
• These bag openers are a must-have for prepping these freezer meals. It holds your freezer bag open to make meal assembly so much easier. I normally freeze my meals in these containers for Instant Pot meals, but for storage purposes, gallon freezer bags were my choice for this boot camp - it makes freezer storage much easier.
• I normally try to put my freezer meals in the fridge the morning of serve day to allow for a little bit of thawing. This allows any ingredients frozen together to break apart and for the meal to cook evenly. If you choose not to do this (and are cooking the meal straight from your freezer), I'd recommend adding 15-20 minutes to your cook time - definitely keep an eye on your meal once the recommend cook time below is over.
