Roasted Red Pepper Soup

Roasted Red Pepper Soup Recipe from Spinach TIger

This roasted red pepper soup recipe almost didn’t happen.

But sometimes, the heavens line up,  and what was going to be a lunch of leftovers suddenly becomes a worthy recipe.

After making sausage and peppers for a party, most of the peppers and onions were left over, and just as I was ready to pitch them, my Vitamix took hold, and a roasted red pepper soup recipe was born.

It’s been soup time around here, and so don’t miss the ones featured below, and wait till you see the cauliflower kale sausage soup that’s coming. I can’t get enough soup of all kinds, but the pureed ones are just so satisfying and usually super health and body loving.

The Health of It – Red Bell Peppers and Onions are High on the Must Eat List

This roasted red pepper soup recipe will fill you up and give you a big punch of healthy.

Red peppers deliver a large amount of Vitamin C, contain antioxidants, are high in Vitamin A, Vitamin B 6 and magnesium. Red bell peppers contain lycopene a cancer fighter, especially for the lungs and prostrate.

There is more good news. Red Bell Pepper is not a a hot pepper, but still stimulates the metabolism, creating a thermogenic effect, without the burn, stimulating weight loss.

Onions are a main staple of Italian food (actually more so than garlic), but I’ve always taken them for granted, never thinking about their nutrition value, only thinking about flavor. Onions are an excellent source of vitamin C, sulphuric compounds, phytochemicals and a flavonoid called quercetin. Onions contai  chromium, which assists in regulating blood sugar and onions help reduce inflammation. Maybe this is why Marcella Hazan put onions as a main ingredient in her famous tomato sauce. 

The Good Taste of Roasted Red Pepper Soup Recipe

This roasted red pepper soup has consistency of a creamy soup and yet there is no cream or cream substitute of any kind. I used just two ingredients, roasted red peppers and onions. You certainly could whisk in some cream or sour cream, but I didn’t find that necessary. I always find it remarkable how creamy roasted vegetables get all on their own when you have a super blender.

The Secret Ingredient

The secret ingredient is fennel (from the sausage flavor). But you can just as easily roast the peppers and onions with olive oil and some fennel seed, and if you dare, just roast a bulb of fennel along with the peppers.

This roasted red pepper soup recipe is minimalist, just peppers, onions and a little bit of olive oil, making this a perfectly healthy, warming wintery soup. It all simply goes into the Vitamix (or similar type super blender) and in a few minutes, you have soup. I had used a variety of bell peppers including an orange, a yellow and two red. Never ever use green; they are too harsh for this recipe.  Do feel free to add in some heat. I used red chile flakes, but sriracha would work too.

    We just finished the soup that we had in the fridge — this will be our next soup. It looks delicious and you’re right red peppers are so good for us. And I am totally in love with fennel. If I could have I would have named one of my children fennel — I’m sure I would have never been forgiven. Can’t wait to make it.
