Mary Jane’s Potatoes: A Family Heirloom

I still remember the first time I tasted Mary Jane’s Potatoes. It was at a sprawling family reunion, a cacophony of laughter, lawn games, and the intoxicating aroma of countless dishes. My great-aunt Mary Jane, a woman with a mischievous twinkle in her eye and an apron perpetually dusted with flour, presented a bubbling casserole dish, its surface a perfect golden brown. One bite, and I was hooked. The creamy, comforting potatoes, infused with the subtle sweetness of caramelized onions, were a revelation. It was a taste of home, warmth, and family, all in one delicious bite. These potatoes have graced our family table for decades, a reminder of Aunt Mary Jane’s love and the simple joys of gathering together.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 45 minutes
• Total Time: 1 hour 5 minutes
• Servings: 6-8
• Dietary Type: Vegetarian

Ingredients

• 6-8 large white potatoes or Yukon Gold potatoes
• 1 large sweet onion, diced to about 1/4 inch pieces (Walla Wallas are best)
• 1/2 cup (1 stick) butter
• 2 cups cream or half-and-half
• 1/2 teaspoon seasoning salt (or to taste)

Equipment Needed

• Large pot
• Colander
• Large bowl
• Grater
• 9×13 inch casserole dish
• Skillet

Instructions

1. Begin by placing the potatoes, unpeeled, in a large pot. Cover them with cold water and bring to a boil over high heat.

2. Boil the potatoes with the skin on until they are barely fork-tender, about 20 minutes. Test for doneness by inserting a fork into the center of a potato. It should offer some resistance but not be completely hard.

3. Once the potatoes are cooked, carefully drain them in a colander. Allow them to cool slightly until they are cool enough to handle.

4. While the potatoes are cooling, prepare the onions. In a skillet, melt the butter over medium heat. Add the diced sweet onion to the melted butter and sauté until just opaque. Be careful not to brown them. You want them to be softened and sweet, but not caramelized. This should take about 5-7 minutes. Set the sautéed onions and butter aside.

5. Once the potatoes are cool enough to handle, peel them. The skins should slip off easily.

6. Using a grater, grate the peeled potatoes into a large bowl.

7. Transfer the grated potatoes into a greased 9×13 inch casserole dish, spreading them evenly across the bottom.

8. Top the grated potatoes with the sautéed onions and butter, distributing them evenly over the surface.

9. Sprinkle the seasoning salt over the potatoes to taste. Remember that you can always add more later, so start with a conservative amount.

10. Pour the cream (or half-and-half) evenly over the potatoes, ensuring that it reaches all parts of the casserole dish.

11. Bake in a preheated 350°F (175°C) oven for about 45 minutes, or until the top is golden brown and the cream has cooked into the potatoes. The potatoes should be bubbly around the edges and slightly firm to the touch.

12. Remove from the oven and let stand for a few minutes before serving.

Expert Tips & Tricks

• Don’t overcook the potatoes: The potatoes should be just barely fork tender when boiled. Overcooking will result in mushy potatoes.
• Use good quality butter: The butter adds richness and flavor to the dish, so use a good quality butter.
• Adjust seasoning to taste: The amount of seasoning salt needed will vary depending on personal preference. Start with 1/2 teaspoon and add more as needed.
• Make ahead: The casserole can be assembled ahead of time and stored in the refrigerator for up to 24 hours. Add about 10-15 minutes to the baking time if baking from cold.
• Add cheese: For an extra cheesy twist, sprinkle shredded cheddar or Gruyere cheese over the potatoes during the last 15 minutes of baking.

Serving & Storage Suggestions

These potatoes are a perfect side dish for any meal. They pair well with roasted chicken, grilled steak, or baked ham. They can also be served as a vegetarian main course alongside a salad or other vegetables.

Leftover Mary Jane’s Potatoes can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, bake in a preheated oven at 350°F (175°C) for 15-20 minutes, or until heated through. You can also reheat them in the microwave, but be careful not to overcook them.

The dish isn’t ideal for freezing due to the cream content, which can sometimes separate upon thawing, affecting the texture. If freezing is necessary, ensure the potatoes are completely cool before placing them into a freezer-safe container. Thaw overnight in the refrigerator and reheat as above, accepting a slightly altered texture.

FAQs (Frequently Asked Questions)

Q: Can I use russet potatoes instead of white or Yukon Gold potatoes?
A: While white or Yukon Gold potatoes are recommended for their creamy texture, russet potatoes can be used. However, they tend to be drier, so you may need to add a bit more cream.

Q: Can I peel the potatoes before boiling them?
A: It’s best to boil the potatoes with the skin on. This helps to retain moisture and prevents them from becoming waterlogged. Peeling them after boiling is much easier.

Q: How do I prevent the top from browning too quickly?
A: If the top of the potatoes is browning too quickly, tent the casserole dish with aluminum foil during the last 15 minutes of baking.

Q: Can I add other vegetables to the dish?
A: Absolutely! Diced carrots, celery, or bell peppers can be added to the onions while sautéing for extra flavor and nutrients.

Q: What if I don’t have seasoning salt?
A: If you don’t have seasoning salt, you can use a combination of salt, pepper, garlic powder, and onion powder. Adjust the amounts to your liking.
