Why are sous vide fajita vegetables so good?
I love fajita vegetables cooked by sous vide because the the vegetables hold their shape, they are crisp and the cells of the vegetables still have juices in them. By searing on a super hot grill pan, cast iron pan or in a grill basket on the grill the vegetables are able to get the char that we all love in our fajita vegetables.
How do you bag up fajita vegetables for sous vide cooking?
- Slice the vegetables in ½" slices.
- In a gallon size bag, drizzle in about a tablespoon of olive oil.
- Add the vegetables in a single layer, but no more than 2 layers.
- Vacuum and seal the bag.
- If using a gallon zip top bag, remove as much air as possible from the bag and seal.
How to sous vide peppers and onions:
- Heat the water bath to 140.
- Submerge the vegetable bag in the water.
- If using a gallon zip top bag, open the bag a tiny bit and slowly lower the bag into the water so the forces the air out of the bag. Close the bag when all the air is pressed out.
- Cook for 1 hour.

Alternately fajita vegetables can be cooked in less time. The temperature needs to be in creased and the time will be decreased.
