How would I bake a lasagna in a half pint mason jar?

First, take off the top of the jar – you definitely don’t want it on..it will explode (or the jar will) when it heats up.

Mason jars are pretty thick, so I don’t think they will shatter under normal use.

Place sideways (not standing up) on a cookiesheet,

Somewhere around 275–300 (no more) for 45 minutes. Until hot inside. Since the lasagna is already cooked, you don’t need bake heat (350).

But mason jars were not the best containers. Pyrix or other flat glassware with more open surface area would have been preferable.

You should be OK with this.

Uuuuhhhhhhhhhhhhhh….............. I don’t have a clue.

Mason jars are made to be boiled in water, I would place it in a pan of water and put it in the oven at bake 350 until hot inside, my guess would be about 45 min to and hour. Sort of a water bath like you do when baking certain desserts except in this case its for the meal. I think the water will keep the glass at a good temperature to keep it anything from happening from the glass while baking.

Good luck with your dinner too bad you couldn’t send me some yummy lasagna.

I have no experience with those jars, I am assuming they are tempered if they can be boiled? It has to be tempered glass or I would not risk heating them. You can always let it all defrost and tranfer the contents to a pan you know is reliable for high temperatures. Then you can bake at whatever the recipe called for in the first place.

I would let it defrost first, take it out of the jar and then bake it.

I have the squat, wide half pint jars, not the taller ones. I baked 120 pies directly in them for my wedding favors, so I know they’re fine in the oven.

But yeah probably will just thaw it in the fridge first.

Since heat expands things, you’ll want to poke a few holes in the lid of your Mason jar.

I would think the glass from the jar would not make it in the oven. It may explode. I wouldn’t do it.

@poofandmook You could defrost them fast in the microwave or even cook them in the microwave. I assume since they are safe for baking they are safe for the microwave. Most frozen lasagnas are a few minutes on high and then an additional amount of time on half power.

like I mentioned above… I baked 120 of these things. It’s not going to explode. That much I can say with total confidence.

@poofandmook Are you talking to me or everyone? I saw that you said that, which is why in my last post I said that if they are safe for baking they probably are safe for microwaving. Meaning, you said they are safe for baking, which I accept and believe now that you confirmed it a few posts up, so probably they are safe for microwaving.
