Slow Cooker Red Kuri Squash and Comté Gratin Step-by-step instructions

Before you start

Before starting, ensure all vegetables are thoroughly washed. Peel the red kuri squash and remove the seeds before cutting it into one-inch cubes. Peel the potatoes and slice them into thin, even rounds, approximately one-eighth of an inch thick.

Grate the Comté cheese using a medium-sized grater to ensure it melts smoothly. Have the cream and spices measured and ready near the slow cooker for seamless assembly.

Instructions

Layering and Assembly

1. 1Layering the base
   Place the bacon lardons at the bottom of the slow cooker basin to ensure they render their fat while cooking. Layer the diced red kuri squash and sliced potatoes evenly over the bacon to build the structure of the gratin.
   Look for Ingredients are evenly distributed in the cooker.
   Tip Ensure the potato slices are uniform in thickness for even cooking throughout the process.

At the end of this phase, the ingredients should be neatly layered within the basin. The bacon lardons should be at the very bottom, followed by the vegetable layers, with the garlic and spices distributed throughout.

The cream should be poured evenly over the top, ready to begin the slow braising process. Ensure the slow cooker is securely covered to maintain the necessary humidity for the vegetables to soften correctly.

Slow Braising

2. 2Adding aromatics and liquid
   Sprinkle the minced garlic and spices over the vegetable layer. Pour the heavy cream evenly over the contents, ensuring it reaches the bottom layers to help braise the potatoes and squash effectively during the slow cooking cycle.
   Look for Cream coats the vegetables and fills the gaps.
   Tip Do not stir the ingredients, as the layering helps the bacon fat permeate the vegetables slowly.

During this phase, the vegetables will soften and release their natural moisture into the cream. The kitchen will begin to smell savory and aromatic. Check that the cream is bubbling gently around the edges of the cooker. The potatoes and squash should be tender and the sauce should start to thicken, transforming into a rich, creamy consistency that coats the back of a spoon.

Final Gratin Finish

3. 3Slow cooking and finishing
   Cover the slow cooker and cook on low for 4 hours. Once the vegetables are tender, sprinkle the grated Comté cheese over the top and cover for an additional 10 minutes until the cheese is melted and bubbly.
   Look for Vegetables are fork-tender and cheese is golden and melted.
   Tip Check the tenderness of the potatoes with a fork before adding the cheese to ensure they are fully cooked.

The final stage involves adding the cheese. Once the cheese is added, the heat trapped inside the slow cooker will melt it into a golden, gooey layer over the vegetables. The dish should look glossy and smell nutty from the melted Comté. The texture should be cohesive and velvety, with the bacon lardons providing a savory, salty bite that cuts through the creaminess of the squash and potatoes.

Common mistakes

A common mistake is overcrowding the slow cooker with excessively large chunks of squash, which can lead to uneven cooking where some pieces remain firm while others become mushy. Another error is failing to slice the potatoes thinly enough, which prevents them from fully absorbing the cream.

Avoid lifting the lid frequently during the cooking process, as this releases heat and moisture, significantly extending the required cooking time and potentially drying out the gratin.

How to tell it’s done

The dish is considered done when the potato slices are completely tender and offer no resistance when pierced with a fork or knife. The liquid should have reduced and thickened significantly, coating the vegetables in a glossy, creamy sauce.

The Comté cheese on top should be fully melted and slightly browned at the edges, indicating the final stage of cooking is complete and the flavors have melded together.
