What is Radish?

  • Radishes are root vegetables that are available all year long. They are related to cauliflower and broccoli, and they have a pungent flavor that mellows as they are cooked.
  • The most popular radish is the red, globe-shaped variety, however more exotic varieties like Daikon and French breakfast radishes are gaining in popularity.
  • Crunchy radishes round out hot or cold dishes and add a boost of nutrition to any dish. Serve this radish casserole with a dollop of sour cream and some sliced green onions.

How To Prepare Radishes?

Radishes do not need to be peeled, although some people prefer to peel Daikons. Simply rinse off any visible dirt and then cut off the green tops and any root that might be remaining. To have radishes at the ready, keep washed and rimmed radishes in dampened paper towels in the crisper section of the refrigerator and use as needed.

Recipe Ingredients

RADISHES – Common red radishes will give the most pop of color to radish casserole, but any variety can be used. Add halved Brussels sprouts, zucchini coins, cauliflower, or broccoli florets for a heartier dish,

SAUCE – A low-carb lifestyle means lots of flavor through healthy fats. Real butter and heavy whipping cream give radish casserole that rich and decadent texture. And leftover bacon grease can be used in place of the butter, plus a dash of sour cream will add extra depth.

CHEESE – Cheddar cheese has a strong flavor, but other cheeses like Swiss or Gruyere (or use a combination) can also be used. Pour a can of cheese soup over the casserole before baking if desired.

BACON – Bacon bits give the final, salty and savory touch to radish casserole, as well as add a pop of protein. Small cubes of ham or leftover ground sausage are also good options and add the same salty complement to the other ingredients.

Refrigerate leftover radish casserole, covered in plastic wrap for up to 3 days and reheat in a 300˚F oven until heated. Cooked radish casserole can also be frozen, just like a potato-based casserole, for up to 3 months. Once frozen and thawed, the texture of a radish will diminish slightly. This is due to the high water content found in radishes.
