Instructions
Prepare Filling
- Lightly coat a large casserole dish with oil. Add onion, garlic, zucchini, carrots, sweet potato, and mushrooms. Bake in preheated oven at 375°F for 25 minutes. Remove from oven and drain off liquid. Return to casserole dish and toss with celery, peas, beans and spices. Distribute evenly.
Prepare Sauce
- Melt butter over medium-low heat in saucepan on stove. Whisk in flour, stirring constantly for 1 minute. Whisk in milk and veggie broth. Bring to boil. Stir in rosemary. Simmer, whisking often, for 3-5 minutes, until thickened.
Prepare Dough Topping
- Stir together flour, sugar, salt, baking powder and soda. Cut in butter using a pastry cutter or two knives until it resembles coarse meal or pea-sized pieces. Stir in egg and milk using a fork just until combined.
Assemble and Bake
- Pour sauce over vegetables in casserole dish. Drop spoonfuls of dough on top in a scattered fashion.
- Bake in preheated oven at 350°F for 20 minutes uncovered. Cover lightly with foil and bake an additional 20-30 minutes or until sauce is bubbling.
Notes
If you don’t have buttermilk you can use a low-fat regular milk or plant-based milk. Add 1 Tbsp vinegar or lemon juice to your measuring cup then fill to 1 cup line.
