How to Make It

Step 1

Preheat oven to 350°.

Remove white papery skins from garlic heads (do not peel or separate cloves). Wrap each head separately in foil. Bake at 350° for 1 hour; cool 10 minutes. Separate cloves; squeeze to extract garlic pulp (you should have about 1/4 cup). Discard skins.

Step 3

Preheat oven to 375°.

Step 4

Heat oil in a large nonstick skillet over medium-high heat. Add shallots; sauté 3 minutes or until softened. Add mushrooms; sauté 5 minutes. Stir in vinegar; cook 1 minute or until liquid almost evaporates. Remove from heat.

Step 5

Place milk, garlic pulp, flour, thyme, salt, and pepper in a food processor; process until smooth.

Step 6

Arrange one-third of potatoes in a 13 x 9-inch baking dish coated with cooking spray. Spread half of the shallot mixture over potatoes. Repeat procedure with remaining potato slices and shallot mixture, ending with potato slices. Pour milk mixture evenly over potatoes.

Step 7

Cover with foil; bake at 375° for 30 minutes. Remove foil; bake, uncovered, 30 minutes. Sprinkle with cheese; bake 15 minutes or until cheese is golden. Let stand 10 minutes before serving.

I think I would change cooking instructions to 425 for 1 hour as after 1.75 hours at 375/400, the potatoes were still not cooked through.

This is one of my go to vegetarian recipes. I love it because I never miss the meat and I eat it as a main dish with a side salad. If you dont like garlic then you wont like this recipe because it really has a powerful garlic bite. I love garlic so I love this hearty recipe.
