Step 1

In a medium-sized pot, whisk together all of the gravy ingredients EXCEPT for the cornstarch & water.

Step 2

Bring to a boil and then turn down to a simmer on medium-low heat for 5 minutes. (This will allow all the flavors to marry.) Remove from the heat.

Step 3

In a separate bowl, whisk together the cornstarch and water to make a cornstarch slurry.

Step 4

Once the pot is no longer simmering, slowly whisk the cornstarch slurry into the gravy a little at a time. Going slow will ensure that no clumps form.

Step 5

The gravy will begin to thicken as soon as the cornstarch is whisked in. Put the pot back on the stove and return to a simmer for an additional 3 minutes.

Step 6

Preheat oven to 450°F.

Step 7

Arrange the potatoes and carrots in a roasting dish with the cauliflower in the center. Be careful not to overcrowd the dish.

Step 8

Place the cauliflower upside-down and pour 1/3 cup of the gravy into it. Give it a good shake to distribute the gravy.

Step 9

Place cauliflower right-side up and brush more gravy on the top to cover it (about 1/3 to 1/2 cup)

Step 10

Add 1/2 cup of vegetable stock to the bottom of the dish (this will help steam the veggies.)

Step 11

Pour about a 1/3 cup of gravy over top of the potatoes and carrots.

Step 12

Cover the dish tightly with a lid or aluminum foil and bake for 40 minutes, brushing the cauliflower with more gravy halfway through.

Step 13

Uncover the cauliflower roast and brush more gravy on. Bake for another 30 minutes (uncovered), brushing with more gravy halfway again.

Step 14

Remove from the oven and serve while hot.
