Preparing Your Slow Cooker
Prepare your slow cooker by coating it with a non-stick agent. Any nonstick cooking spray or oil will work. Olive oil and avocado oil are my go-to coatings.
NOTE: some slow cooker inserts come with a nonstick surface. Use of a non-stick agent is still suggested. However, oil is sometimes recommended rather than spray to protect the longevity of the non-stick surface. Check your slow cooker's manual if you have any concerns.
Alternatively, you can choose to use a slow cooker liner.
Cooking
- 🫑 Start by washing your peppers. Cut them in half and remove all seeds, stems, and white membrane (the pith and the ribs)
- 🫑 Grease slow cooker as mentioned above with a few tablespoons of olive oil
- 🫑 Add pepper halves to the bottom of the slow cooker however they fit best
- 🫑 Cook on high for 4-5 hours
- 🫑 Allow cooked peppers to cool. Skins will peel and slide off easily by hand

🔁Substitutions
- Use any kind of pepper—bell, sweet, banana, or cubanelle.
- Swap the olive oil with any neutral flavored oil (like avocado oil) in this recipe. The oil is more for avoiding sticking and easy clean up than it is for flavor
Storing
Storef Freshly roasted peppers in a glass, airtight container. They will last for 5-7 days. Alternatively, freeze roasted red peppers for up to 3 months.
Allow frozen peppers to thaw overnight in the refrigerator before serving.
😉Hints & hacks
- Storing roasted peppers in olive oil and pepper juices will enhance the flavor and help them last longer.
- This is a great crock pot dish to make for a crowd. Make a large batch using a larger slow cooker to fit as many peppers in as possible.
- Marinate your roasted peppers by adding them to a jar with olive oil, salt, balsamic vinegar and fresh garlic cloves. This makes them even more delicious!
- I am generally a fan of slow cooker liners. Easy clean up!!
- In the market for a new slow cooker?? I love mine!
FAQs
Yes! Cut and remove the seeds after they have cooled.
Yes! Just reduce cook time slightly and watch for blistering.
Peeling is optional, but it makes the peppers smoother and more versatile.
Red, yellow, and orange peppers are my favorite to roast because of their naturally sweet flavor. Green peppers can be roasted as well, but will have a stronger, more bitter flavor.
