Here are the simple steps to freeze blue hubbard squash:

Step 1: Select and Prepare the Squash

The first step in freezing blue Hubbard squash is to carefully select and prepare the squash to ensure optimal taste and quality after freezing. Here’s how you can do it:

1. Choose Fresh and Ripe Squash: When selecting blue Hubbard squash for freezing, opt for ones that are fresh and ripe. Look for squash that feels heavy for its size, indicating that it is dense and full of moisture. Avoid squash that feels light or has soft spots, as these may indicate spoilage.

1. Prepare the Squash: Begin by placing the blue Hubbard squash on a stable surface, such as a cutting board. Using a sharp knife, carefully cut off both ends of the squash. This will create flat and stable surfaces, making it easier to handle during the peeling and cutting process.
2. Peel the Squash: Stand the squash upright on one of the flat ends. With a steady hand, use the knife to peel off the tough skin, working your way from the top to the bottom. Ensure that you remove all of the skin, as it can be tough and undesirable when frozen. Take your time and be cautious while peeling to avoid any accidents.
3. Cut the Squash in Half: Once the squash is peeled, cut it in half lengthwise. This will expose the inner cavity, which contains the seeds and pulp. Use a strong and stable grip on the squash to safely make the cut. You can apply gentle pressure with the knife and use a rocking motion to guide the blade through the squash.
4. Remove Seeds and Pulp: After cutting the squash in half, you’ll find a cavity filled with seeds and pulp. Take a spoon and scoop out the seeds and pulp, discarding them. Ensure that you remove all of the seeds and pulp, as they can affect the texture and taste of the frozen squash.
5. Cut into Smaller Pieces or Slices: With the seeds and pulp removed, you can now proceed to cut the blue Hubbard squash into smaller, manageable pieces or slices. Consider the intended use of the squash when deciding on the size of the pieces. Some prefer larger chunks for roasting or mashing, while others may prefer smaller pieces for soups or stews.

By peeling and cutting the blue Hubbard squash, you’ll be able to prepare it in a way that is convenient for freezing and future use. Remember to exercise caution while handling the knife and take your time to ensure precise cuts and a safe kitchen environment.

Step 3: Blanch the Squash

Blanching is a crucial step in the process of freezing blue Hubbard squash. It helps to preserve the squash’s color, texture, and nutritional value. Follow these steps to blanch the squash properly:

1. Prepare a Large Pot: Take a large pot and fill it with water, leaving enough room for the squash to be submerged. Place the pot on the stovetop and bring the water to a rolling boil over high heat. The pot should be large enough to accommodate the quantity of squash you are blanching.
2. Add the Squash: Carefully place the blue Hubbard squash pieces or slices into the boiling water. Ensure that the squash is fully immersed in the water. You can use a slotted spoon or tongs to safely lower the squash into the pot.
3. Blanching Time: Allow the squash to cook in the boiling water for 2-3 minutes. The exact blanching time may vary slightly depending on the size of the squash pieces or slices. Larger pieces may require slightly longer blanching, while smaller ones may be ready within 2 minutes. The goal is to partially cook the squash without fully softening it.
4. Ice Bath Preparation: While the squash is blanching, prepare an ice bath by filling a large bowl or sink with cold water and adding ice cubes. This ice bath will be used to cool down the blanched squash quickly and halt the cooking process.
5. Transfer to the Ice Bath: After the designated blanching time, use a slotted spoon or tongs to remove the blanched squash from the boiling water and immediately transfer them to the ice bath. Submerging the squash in the ice bath rapidly cools it down, preventing any further cooking and preserving its vibrant color and texture.
6. Allow Cooling: Leave the squash in the ice bath for the same amount of time it was blanched. This ensures that the squash cools down completely and stops the cooking process. Stir the squash gently in the ice bath to ensure all pieces cool evenly.
7. By blanching the blue Hubbard squash, you not only retain its appealing color and texture but also help to preserve its nutritional value. Blanching prevents enzyme activity and bacterial growth, which can affect the quality of the frozen squash.
