How to Make Dad’s Creamy & Cheesy Au Gratin Potatoes
Step 1: Preheat the Oven
Preheat your oven to 375 degrees F. This step is crucial as it ensures that your au gratin potatoes bake evenly from the start. Grease a 2-quart square baking dish with nonstick spray or butter so nothing sticks!
Step 2: Arrange the Potatoes
Layer sliced potatoes in three tight slanted rows in your baking dish. Remember not to pack them too tightly; they need space to cook properly. Nestle those onion slices between the potato layers—this adds great flavor as they soften!
Step 3: Make Your Sauce
In a saucepan over medium heat, melt the butter. Once it’s melted, whisk in a little flour before slowly adding in almond milk while whisking vigorously to avoid lumps. Bring this mixture to a simmer; it should look like creamy gravy—smooth and luscious!
Step 4: Add Cheese and Seasonings
Once simmering, lower the heat and stir in shredded cheddar cheese, garlic powder, salt, and pepper. Give it a taste—this is where you can adjust seasoning if needed! The cheesy aroma will be hard to resist.
Step 5: Pour Over Potatoes
Now it’s time to pour that glorious sauce over your arranged potatoes and onions evenly, ensuring everything is covered well. Don’t worry; it will get even creamier while baking away!
Step 6: Bake Covered
Cover the pan with foil and pop it in the oven for about 45 minutes. This helps steam the potatoes so they get tender without drying out.
Step 7: Add Toppings and Finish Baking
After 45 minutes, remove the foil and sprinkle gruyere cheese and parmesan on top. Put it back in the oven for another 30-45 minutes until everything is bubbly and golden brown on top—just like my dad used to make! When done, garnish with fresh chopped parsley before serving.
Enjoy every cheesy bite of Dad’s Creamy & Cheesy Au Gratin Potatoes—you’ll be going back for seconds!
Pro Tips for Making Dad’s Creamy & Cheesy Au Gratin Potatoes
Making this dish is a delightful experience, and with a few handy tips, you can ensure it turns out perfectly every time!
- Use Yukon Gold Potatoes: Their natural creaminess makes them ideal for au gratin dishes, giving a rich texture that’s hard to beat.
- Slice Evenly: Keeping the potato slices uniform (about 1/8th inch) ensures they cook evenly and achieve that perfect creamy consistency throughout.
- Don’t Skip the Foil: Covering the dish with foil during the first part of baking helps steam the potatoes and cook them through before browning the cheese on top.
- Taste as You Go: Always taste your sauce before pouring it over the potatoes. Adjust salt and pepper to your preference for a flavor that’s perfectly tailored to your palate.
- Let It Rest: After baking, allow the dish to sit for about 10 minutes before serving. This resting period helps the sauce thicken up a bit more, making each scoop easier to serve.
