Part 3 of Sheet Pan Dinners Freezer Meal Boot Camp is today! And I must say – this is the prettiest meal in this boot camp line-up. Sheet Pan Rainbow Beef is loaded with yummy veggies and tender steak. As a matter of fact, this one is a full meal in and of itself – no side item needed!

When you're in need of a super simple dinner on limited time, this is one you're going to want to have in your freezer. It's as easy as lightly defrosting and popping a pan in the oven.

Here's how this sheet pan dinners series works…

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 1/2-1″ 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.
