Do you do ‘Meatless Monday’ meals and need a fresh idea? This Roasted Garlic-Herb Mushrooms and Butternut Mash is easy and healthy, plus this is a diabetic-friendly meal. The earthy taste of the garlic-herb mushrooms pairs so well with the natural sweetness of the butternut squash.
Mushrooms are well known as a side dish, and they are so good added to sauces, pastas or just enjoyed raw in salads and veggie trays. They are high in nutrients, low in calories, taste delicious and work well in a diabetic diet.
There is a myth that mushrooms are a good protein replacement for beef, chicken or fish. Maybe it is a myth as it appears one-ounce of raw mushrooms has only one gram of protein. Compare that to four ounces of raw chicken breast at eighteen grams of protein. So….four-ounces of raw mushrooms is a mere four-grams of protein.
However, mushrooms are little sponges, and they are full of water. But when you cook those little goodies, they lose all their water and shrink to about half their volume. What you end up with are condensed, umami-flavored morsels. But it is ok to eat a double portion. 🙂
Our seven-year-old grandson loves mushrooms, and he came for a visit so I made this roasted garlic-herb mushrooms and butternut mash special for him. Grandmas have to spoil those little critters while we can as they grow up so fast. I was surprised that he liked mushrooms so much as it seems an odd veggie choice for a seven-year-old.
How to Prepare Roasted Garlic-Herb Mushrooms and Butternut Mash
In keeping with a Meatless Monday, I roasted butternut squash and gave it a good mashing, then topped it off with the roasted mushrooms. There is no peeling of the butternut here, just cut it open then scoop out the seeds and stringy membrane. Brush the inside with a little oil, give each section a good dose of salt and pepper then roast in a hot oven until tender. After the squash has cooled enough to handle, scoop the flesh out and mash it up with butter. Alternatives mashable vegetables for the butternut could be:
- Sweet Potato
- Celery Root
While the butternut was roasting, I sliced the mushrooms, tossed them with a mixture of oil and lots of garlic, then spread them on a baking sheet. When the butternut came out of the oven, the mushrooms went in. They roasted for ten minutes then I removed the baking sheet from the oven and poured off the accumulated liquid. That super flavorful liquid made a little bit of sauce, and I tossed it with the mushrooms. Serve with a drizzle of lemon juice and a thyme sprig garnish.
That little guy, Sheamus, cleared his plate except for the broccolini. But he knew there was a slice of Chocolate Peanut Butter Layer Cake waiting for him. Ha Ha….

Transfer the sheet pan to the center of the oven and roast for 45-50 minutes. Remove from the oven and allow to cool, then scoop out the squash pulp and mash with the butter.
For the Mushrooms:

- Brush and rinse the mushrooms to remove any soil or debris. Cut in half and place in a large bowl.

After the butternut is mashed, cover it and keep it warm. Or, reheat it briefly in the microwave before serving with the mushrooms.
I used Crimini mushrooms in this recipe but any type of mushrooms will work.
