How to Cook a Rumbo Squash: an illustrated tutorial

The thought of cooking a Rumbo squash can be quite scary; frightening enough to send many cooks to the internet. Every few weeks someone arrives at my blog by asking  how to cook a Rumbo squash. Finally I’m answering the question. After all, it is quite daunting to have a 13-18 pound squash sitting on your cutting board.

Store squashes resting on their stems.

For the best flavor and sweetness harvest your Rumbo squashes when the entire skin has turned orange-tan. Leave the stem on the squash. Wash and dry then store in a cool place. The ideal temperature is 55°F. My unheated basement works well.

After harvest store the squash upside down on a shelf, resting on its stem and 1-2  spots of the skin. This position prevents moisture from being trapped under the squash, leading to mold.

Cooking a Rumbo Squash

1) Wash squash. Break off stem.

The challenge: a 14 pound Rumbo squash

2) Cut in half. I like to cut at a deep rib. It’s even better if you can find two deep ribs opposite each other.

Cut in two.

3) Scrape out seeds and stringy fibers with a large spoon.

4) Save the seeds in a colander, remove the stringy fibers and rinse.

Save the seeds to roast later.

5) Now for the tough part: you need a very large pan to roast this squash. The pan must be sturdy because this squash is heavy. The pan must have sides because this squash releases  lots of juice during cooking. This roasting pan, which came with my gas oven, is 15″x15.5″ and 1.25″ deep.

I wrap the cut edge of the squash with foil. The foil traps juices next to the squash. Without foil the juice spreads into the pan and evaporates away then the sugary residue burns.

Alternately – use a smaller roasting pan for each half. With two small pans the squash is easier to lift. I cook smaller – 10 pound – Rumbos cut side up in my covered turkey roaster.

6) Bake at 350° F. for 70-80 minutes. This squash took an hour and 15 minutes.

7) If your oven has a vent, you can dry the seeds under or over the vent while the squash cooks. Use a metal colander, because a plastic colander would melt. Stir the seeds occasionally to prevent them from sticking together and to dry them evenly. Use a pot-holder to handle the colander – it will be burning hot. (Guess how I know.)

8) The Rumbo is cooked when a fork can be thrust easily through the skin, into the squash. Test at the thickest part of the squash. A lot of liquid in the pan is another sign it’s cooked.

9) Remove the pan from the oven with care. It contains 2-4 cups of scalding hot liquid which could inflict severe burns if sloshed over your hands. If the pan will be too heavy to lift, cook each half squash in a separate smaller pan. Alternately – remove the liquid from the pan before lifting the pan. (Step 11)

10) Allow the squash to cool for a bit – at least 10 minutes.

11) Remove the liquid from the pan with a turkey baster, filling a glass jar. After clearing the foil , carefully lift the edge of the squash. There may be lots more juice trapped underneath. I save the juice to use as part of the broth in soup.

12) Roll over the squash halves and let them cool some more. The cut edges will flop together and trap heat. I cut each half in two, to open it up.

Rolled over, cut in two, and cooling.

13) Using a large spoon, scoop the squash flesh out of the skin from between the ribs.

14) Enjoy. This 14 pound squash yielded 6.5 pounds of squash flesh and 3.5 cups juice.  Substitute Rumbo squash into any recipe calling for pumpkin or other winter squashes. I’ll use it for squash bread and soup and roast the dried seeds. Rumbo is particularly good in soups because it is so juicy. For breads and cakes, I drain away some of the juice before using.
