HOW TO MAKE
Start by gathering the equipment for the recipe and then the ingredients.
- Cutting board
- Stir spoon
- Measuring spoons
- Measuring cups
- Medium-sized skillet
Olive oil, onion, garlic, chicken broth, broccoli florets, cauliflower florets, evaporated milk, butter, flour, soy sauce, ground pepper, and cheddar cheese.
Nope! You do not need to use an immersion blender, food processor or blender for this recipe. You can puree the soup if you prefer a smoother soup but it is not necessary.
Fresh is best for this recipe. If you do choose to use frozen vegetables, thaw before adding to the stockpot.
Start by sautéing the onions in a stockpot.
“Sautéing” is a cooking method that cooks the ingredient(s) quickly in a small amount of oil or fat. For this recipe, you will sauté the onions in olive oil.
Add 1 TBSP of olive oil to a skillet over medium-high and heat for 1 minute. Then, add the diced onion and sauté until translucent (about 3-4 minutes). “Translucent” means that you should be able to almost see through the onions. Stir the onions – watching for your onions to turn from solid white in color to translucent while shrinking in size. The onions will also start smelling sweet because sautéing helps onions develop a sweet flavor.
Next, add the minced garlic to the stockpot and cook with the onions for an additional 1 minute.
Add the broccoli and cauliflower to the stockpot. This recipe requires 2 heads of broccoli and 1 head of cauliflower to be broken into smaller pieces. You can use a measuring cup to measure 5 cups of both the broccoli and cauliflower florets into the stockpot.
Then, add 1 cup of chicken broth to the stockpot.
INGREDIENT SWAP: Swap the chicken broth for 1 cup vegetable broth or 1 cup water.
Using chicken or vegetable broth will add more flavor to your soup, but water is a good option if broth isn’t available.
Cover the stockpot with the lid.
Then, steam the vegetables over medium-high heat for 6-7 minutes. “Steaming” allows a liquid to heat to a temperature where steam is created, which then cooks the food. In this recipe, the broth creates the steam that cooks the broccoli and cauliflower.
Next, you will add the liquids and spices. To the stockpot, add the rest of the chicken stock, evaporated milk, soy sauce, and pepper.
Bring to a low simmer. When “simmering”, keep the pot at a heat where there are slow bubbles rising to the surface of the broth. If the bubbles are rapidly coming to the surface of the broth, turn the heat to a lower setting.
It is time to make a roux. While the soup is coming to a simmer, make the roux in a separate skillet. I use a medium-sized skillet.
MAKING A ROUX
Mixing fat, flour and liquid together over heat makes a roux. This helps to create a thick & creamy soup.
For this soup recipe, you will use butter as the fat. Melt the butter over medium-low heat in the skillet. Then, whisk in the flour. For the liquid, you will use some hot liquid from the soup. Using a measuring cup, add 1/4 cup of hot liquid from the stockpot into the skillet. Whisk the liquid into the flour mixture. Repeat adding 1/4 cup of hot liquid 7 more times until you’ve whisked in a total of 2 cups of liquid into the flour mixture.
Now, you will use the homemade roux to thicken the soup. Gently whisk the roux from the skillet into the stockpot filled with soup.
Continue to cook the soup for about 3-4 minutes. During this time, watch for the soup to slowly thicken.
Now for the best part! Add the cheese. Stir the 2 cups of cheese into the soup until completely melted. Then, serve for a weeknight dinner, virtual learning lunch or lunchbox meal.
