Begin by preheating your oven and preparing your ingredients for smooth sailing. This guide walks you through each part, drawing from the recipe’s directions to make it foolproof.

First Steps and Roasting

Preheat your oven to 400 degrees Fahrenheit and get your ingredients ready. Toss 2 pounds of cubed butternut squash in olive oil and roast it for about 30 minutes until it’s tender and caramelized. While that’s happening, focus on caramelizing 1 large onion in 2 tablespoons of butter and 1 tablespoon of olive oil over low heat for around 45 minutes.

Blend everything until smooth using an immersion blender or a regular one for that creamy finish.

For a lower-carb twist, swap in roasted cauliflower or use variations like shredded chicken for added savoriness.

Vegetable, Sauce, and Seasoning Modifications
