Heat oven to 400°F. Grease 9x13-inch baking dish. Melt butter in a large sauté pan over medium-high heat. Add onion, sauté for 4-5 minutes until soft & translucent. Add garlic, sauté for an additional 1-2 minutes until fragrant. Stir in the flour until it is evenly combined, & cook for 1 more minute.
Gradually pour in stock, & whisk until combined. Add in milk, salt, pepper, 1 tsp thyme, & whisk until combined. Continue cooking for an additional 1-2 minutes until sauce begins to simmer around the edges of pan & thickens. Then remove from heat & set aside.
Spread half of sliced potatoes in an even layer on the bottom of pan. Top evenly with half of cream sauce. Sprinkle evenly with 1 cup of shredded cheddar cheese, & all of Parmesan cheese. Top evenly with remaining sliced potatoes, other half of cream sauce, & remaining 1 cup of cheddar cheese.
Cover pan with aluminum foil & bake for 30 minutes. Remove foil & bake uncovered for 25-30 minutes, or until potatoes are cooked through. Transfer pan to a cooling rack, sprinkle with remaining teaspoon of thyme & extra Parmesan.
