Spaghetti is one of the best meals because it’s so comforting and familiar. We’ve all had it when we were kids, and when we have kids, we make it for them. The problem is that you can’t seem to store it for long. And to get the best flavor, you must admit you have to spend hours simmering and stirring. Or maybe you can only eat your mom’s cooking, but you can only have it when she comes over. So here’s how to freeze dry spaghetti sauce so you can store it long-term and have a ready meal in minutes.

What Kind Of Spaghetti Sauce Can I Freeze Dry?

You can freeze-dry any kind of spaghetti sauce. The best one, of course, is homemade. You know what’s in it, and it’s got the flavor you’re craving. There’s nothing like having the taste you grew up in and having it with you whenever you need it.

If you don’t have your own special recipe, you can try these. Just make sure that you taste before you freeze dry because this will be how your batch of sauce will taste.

If you create your pasta sauce from scratch, feel free to use your freeze-dried food supply. You can use your freeze-dried tomato, onion, beef, thyme, and whatever ingredients you need for a fantastic sauce.

You can also go for just plain tomato pasta sauce or make your freeze-dried meal more flavorful by adding meat. There’s no limit or restriction on what kind of sauce you’d want to make, so go crazy, frugal, or extravagant if you want to.

But if you’re going to use meat, use lean ones. If you can’t get lean ones, that’s okay. Let the sauce cook for a few or several hours, then skim off the fat from the surface. This may take out a layer of flavor out of the spaghetti sauce but will help make it last longer.

That said, don’t use too much expensive oil when cooking the sauce. You’re just going to take out the excess, so it would be a waste.

Do I Pre-Freeze?

Pre-freezing is optional but can go a long way, especially if you have a runny sauce. The more liquid your food has, the longer it takes to freeze. To help cut the freeze-drying time and wait time if you have a lot of food lined up, pre-freeze your spaghetti sauce.

Freezing in the deep freezer overnight or for several hours produces large ice crystals. The bigger the size of ice crystals, the easier it is for the machine to sublimate it into water vapor. As a result, the freeze-drying process is faster. Of course, this means leaving behind air pockets, but that won’t matter. You’ll reconstitute the sauce in water, so this airy texture isn’t going to affect your eating experience.

If you’re going to pre-freeze, use the same trays in which you’ll be freeze-drying your sauce. Or you can use a different tray, but make sure it’s half in size shorter. The height of the frozen sauce also shouldn’t be higher than the lip of your freeze dryer tray. The thicker the sauce layer, the harder it is to freeze-dry.

Not only do they take little storage space, but they’re also lightweight. You can put them in your bag and not worry about breakage when camping or hiking.
