I’ve been on a roasted red pepper kick lately!  I’m always amazed at the taste transformation that occurs in a red bell pepper when roasted and how it goes from sweet to rich, earthy and complex.  Perfect for Cauliflower and Sweet Potatoes in Roasted Red Pepper Mole!

The best and tastiest roasted red bell pepper is one that you roast yourself.  It’s not a complicated process, it’s just time-consuming.

Tips for roasting peppers:

You can roast peppers under a broiler, but you’ll need to watch them closely.  Another roasting option is to hold them over a gas flame, but that takes too much time for me.  I prefer a hands-off method, so instead, here’s what I do:

  • I roast them in a super-hot 450-degree oven near the heating element (which in my oven is at the top).  It takes a little longer, but I don’t have to watch them as closely.
  • Turn as necessary to char them evenly.
  • As they blacken and blister, you’ll see the skin start to pull away from the rest of the pepper.
  • Immediately upon removing from the oven, place a sheet of aluminum foil or another baking sheet over the peppers.  (You want to fully enclose them.)
  • Let them sit for about 20 minutes.  The steam produced will allow the skin to pull off easily.  If some of the skin stays behind here and there, I don’t worry about it.  Pull off all you can that comes off easily.
  • When peeling and removing the seeds, resist the urge to do it under running water.  It might make it easier to get the seeds out, but you’ll be rinsing away flavor.

If using roasted red peppers in a jar, make sure they’re packed in water–not a brine.  Here’s a taste test conducted by The Huffington Post you might find helpful.

What is a mole (moh-lay)?

Moles are common in Mexican cuisine and always include some type of chili pepper, nut or seed and various spices.  The preparation can be quite involved and the deep, richly flavored sauce that results is generally best paired with meat or poultry.

My version with red bell peppers as the base is perfect with vegetables–in this case cauliflower and sweet potatoes–for a satisfying vegan meal.

Rather than cooking the cauliflower in the sauce, I roast it while the bell peppers steam.  I L-O-V-E roasted cauliflower and feel the texture is better maintained this way.  Simply heat through in the sauce at the end.
