Mexican Chile Relleno Sauce

Whoa baby. Who needs a little spice in their life? This Mexican Chile Relleno sauce will do just the trick. The spices combined with the jalapeno flavor will really kick those taste buds into gear.

We do not get nearly enough whole grains in our diets typically, so we could really use some wherever we can get it. Adding whole wheat flour to this sauce helps us get those important nutrients from whole grains that we really need for our cells to function properly. The whole wheat option can help increase your iron intake as well as a great source of fiber and B vitamins, while adding a healthy dose of fiber.  

To prepare this recipe, you will need to start by heating up olive oil in a saucepan for a few seconds and then tossing in your onions, garlic, jalapeno, and pepper for about five minutes over medium heat.  Slowly add in the flour and mix into the sauteed veggies.  This will begin to form a pasty-grainy mixture.  Cook this up for another two minutes. Transfer everything from the pan into a blender and add in fresh tomato as well.  Blend everything together until it is a nice thick paste consistency.  In a pot over medium heat, add the contents of the blender and mix in three cups of water.  Cook this all together for 15-20 minutes.  For the last five minutes of cooking, add in oregano and cilantro.  Throw in a dash of salt and you’ve got yourself some authentic cuisine right there.

Put this together with some beans, rice, and sauteed veggies for a full, well-balanced meal.  You can make the sauce ahead of time and store in a glass container, such as a mason jar, for up to one week.  Have you ever made your own Chile Relleno Sauce before?

    I buy pre-made chiles rellonos at the Bueno Foods warehouse in Albuquerque. They are popular in New Mexico, and I often see them on restaurant plates. They come frozen and cook up nicely in the toaster oven. Good amount of heat in the chiles and crisp crust.

    This sauce was spot on for authenticity. But add the oregano a pinch at a time, the tsp. would be much too strong. Also, I used masa harina instead of the whole wheat flour, which I did not have on hand. It added a great traditional taste!

    This being Thanksgiving weekend and not fresh tomato season, I used a 16-oz. can of organic chopped San Marzano tomatoes and it was just fine.

    First time making Chile Rellenos and looking for a sauce recipe. Found a couple. I thought this recipe looked easy enough but worried that it also looked so Bland. Was I surprised ! Family absolutely loved the outcome. I did read all the previous comments about not so much Oregano, plus I think I used twice the Tomatoes. This is a Keeper.
    Thanks from glo.
