Are Jalapeños OK on Keto?

They sure are! One jalapeño contains only 0.5g net carbs.

How Can I Cut Jalapeños Safely?

First, put on a pair of disposable gloves. Trust me, you don’t want to get the hot stuff on your hands! (If you do, you can use the tricks in this article to remove the burn.)

Then, cut a jalapeño in half lengthwise. Use a spoon to scrape out the white membrane, removing the membrane starting at the bottom of the pepper, working your way to the top.

    To make this even easier ( and only 4 ingredients) I buy the Publix Jalapeño Popper Dip , and the Publix already cooked sliced chicken breast and I put the sliced pre cooked chicken breast in the bottom of my casserole dish then put the entire thing of the Publix jalapeño popper dip on top and spread it out then I put an entire package of bacon ( that I cooked In the oven @425 for 10-12 minutes perfectly cooked ) that I cut into chunks on top then top with shredded cheese typically mild cheddar and mozzarella and top with more chunks of bacon , cover with aluminum foil and bake at 350 for 25-30 minutes 😋 and it’s absolutely amazing!!! Plus the entire prep time is like 3 minutes lol 😆 and seriously everyone I’ve ever made it for begs me for the recipe and it will literally be the best thing you’ve ever tasted

    • Hi Hallie! Yes. It can be stored in the fridge for up to two days – just cover the top with saran wrap or foil.
