Asparagus doesn't get enough credit as a gut-health powerhouse. It's one of the most concentrated plant sources of inulin, a prebiotic fiber your Bifidobacterium and Lactobacillus specifically thrive on. Roasting it brings out a natural sweetness and a caramelized edge that makes it way easier to eat a full serving than the steamed version you might remember from childhood dinners. Five minutes of prep, twenty in the oven, and you've got a side dish that's actually working for your microbiome.

Why This Is Good for Your Gut
Asparagus contains 2-3g of prebiotic inulin per 100g — one of the highest concentrations of any vegetable. Inulin specifically feeds Bifidobacterium and is fermented to produce butyrate, the primary fuel for colon cells. Garlic adds additional inulin. Olive oil's polyphenols selectively support beneficial bacteria.
Double the batch. It reheats fine and makes a great addition to grain bowls all week.
