Ingredients

For the Pie Base

1 deep dish frozen pie crust, do not thaw
1 medium Vidalia onion (substitute another sweet onion variety if needed)

For the Custard Filling

5 large eggs, preferably free-range for richest flavor
1 /2 cup whole milk, organic preferred
1 /2 cup heavy cream (omit the cream and use more milk if you prefer)
1 teaspoon onion salt
1 /2 teaspoon fresh cracked black pepper

For the Cheese Layer

1 cup shredded sharp cheddar cheese, preferably white (heap your measuring cup generously)

Instructions

Preparation

1 Preheat your oven to 400°F (200°C). If you’re transferring a frozen crust to your own pie plate, butter your pie plate first with a light coating, then gently pry the frozen crust out of its tin using a bench scraper or your fingers. The butter helps prevent sticking and adds extra richness to the bottom crust.
2 Peel and slice the Vidalia onion into 1/8-inch thick rounds using a sharp knife or mandoline slicer for perfectly uniform slices. A mandoline slicer gives you restaurant-quality precision and ensures even cooking throughout the pie. Cut most of the rings into halves or quarters for easy distribution, while leaving a few whole rings intact for an attractive top garnish.

Making the Custard

3 In a medium mixing bowl, gently whisk the 5 large eggs just until the yolks and whites are combined – don’t create too much foam as this can affect the final texture. Gradually whisk in the 1/2 cup whole milk and 1/2 cup heavy cream until completely smooth. The combination of milk and cream creates the perfect custard consistency that’s rich but not overly heavy.
4 Season the custard mixture with 1 teaspoon onion salt and 1/2 teaspoon fresh cracked black pepper, whisking until evenly distributed. The onion salt amplifies the sweet onion flavor while the black pepper adds a subtle warmth that complements the creamy base.

Assembly and Baking

5 Spread the 1 cup shredded sharp cheddar cheese evenly across the bottom of your prepared pie crust, creating a cheese foundation that will melt and bind with the custard. Follow with most of the sliced onions, distributing them evenly but reserving your prettiest whole rings for the final presentation.
6 Carefully pour the egg and cream mixture into the pie crust – it should fill to just below the rim without overflowing. Arrange the reserved whole onion slices artfully over the top of the pie for an elegant finish. Place the assembled pie on a rimmed baking sheet to catch any potential overflow and make transferring easier.
7 Bake for 55-60 minutes until the pie is puffed, golden brown, and set in the center with just a slight jiggle when gently shaken. If your oven bakes unevenly, rotate the pie halfway through the baking time to ensure uniform browning. The top should be beautifully golden and the custard should be firm to the touch.
8 Allow the pie to cool for 10-15 minutes before serving – this resting time helps the custard set properly for clean slicing. Serve warm for the ultimate comfort food experience, though it’s equally delicious at room temperature. Store any leftovers covered in the refrigerator, where they’ll keep for up to 3 days and reheat beautifully in a low oven or microwave.

Nutritional Information and Health Benefits

Key Nutritional Highlights

This Vidalia onion pie provides approximately 280 calories per serving when cut into 10 generous portions. Each serving delivers 14 grams of protein from the eggs and cheese, 18 grams of carbohydrates primarily from the crust and natural onion sugars, and 18 grams of fat from the dairy components. The pie offers 2 grams of fiber and significant amounts of calcium, vitamin A, and B vitamins from the egg and dairy combination.

Health Benefits of Main Ingredients

Vidalia onions are rich in quercetin, a powerful antioxidant that supports heart health and has anti-inflammatory properties. The eggs provide complete protein with all essential amino acids, plus choline for brain health and lutein for eye health. Sharp cheddar cheese contributes calcium for bone health and vitamin K2 for cardiovascular support. The combination of whole milk and cream provides conjugated linoleic acid (CLA), which may support healthy metabolism when sourced from grass-fed dairy.

Dietary Considerations

This recipe contains eggs, dairy, and gluten, making it unsuitable for those with these specific allergies. However, it’s naturally low in sugar and provides a good balance of macronutrients. The high protein content helps stabilize blood sugar levels, while the healthy fats promote satiety. Each serving provides about 15% of your daily calcium needs and 20% of daily protein requirements for most adults.

Perfect Pairing Suggestions

Beverage Pairings

A crisp Sauvignon Blanc or Pinot Grigio complements the sweet onion flavors beautifully without overwhelming the delicate custard. For beer lovers, a light wheat beer or Belgian witbier provides the perfect refreshing contrast. Non-alcoholic options include sparkling water with lemon or iced green tea to cleanse the palate between rich, creamy bites.

Side Dish Recommendations

Serve alongside a mixed arugula salad with balsamic vinaigrette to cut through the richness with peppery greens and bright acidity. Roasted asparagus with lemon zest provides a fresh, spring-like contrast that pairs naturally with the onion’s sweetness. Herb-roasted fingerling potatoes make this a complete, satisfying meal, while fresh fruit salad adds a light, refreshing finish.

Complete Meal Ideas

For brunch entertaining, pair with crispy bacon strips and fresh berries for a restaurant-quality spread. As a light dinner, serve with grilled chicken breast and steamed broccoli for a well-balanced, protein-rich meal. For vegetarian dinners, add a quinoa tabbouleh and roasted Mediterranean vegetables for a complete amino acid profile.

Occasion Suggestions

This pie shines at weekend brunches, potluck dinners, and casual entertaining where you want something impressive but not fussy. It’s perfect for Easter brunch, Mother’s Day lunch, or book club meetings where you need something that can be served at room temperature and still taste amazing.

Pro Tips and Troubleshooting

Professional Techniques

Pre-bake your pie crust for 5 minutes before adding filling to prevent a soggy bottom – this technique, called blind baking, creates a moisture barrier. Let your eggs come to room temperature before whisking for smoother custard integration. Strain your custard mixture through a fine-mesh sieve to remove any lumps and create restaurant-quality smoothness.

Common Mistakes to Avoid

Don’t overbeat the eggs, which creates too much air and can cause the custard to puff excessively then collapse. Avoid opening the oven door frequently during baking, as temperature fluctuations can cause uneven cooking. Never skip the cooling period – cutting too early results in a runny, unset custard that won’t hold its shape.

Storage and Reheating

Store covered in the refrigerator for up to 4 days. Reheat individual slices in a 300°F (150°C) oven for 10-12 minutes to restore the crispy crust texture. Microwave reheating works but may soften the crust. This pie freezes beautifully for up to 3 months – thaw overnight in the refrigerator before reheating.

Make-Ahead Strategies

Assemble the entire pie up to 24 hours in advance and refrigerate covered. Add 5-10 minutes to the baking time if baking from cold. The flavors actually improve overnight, making this perfect for stress-free entertaining.

This Vidalia onion pie proves that sometimes the most elegant dishes are built on the simplest foundations – sweet onions, creamy custard, and a little patience while the oven works its magic. Whether you’re serving it for a special occasion or just because Tuesday deserves something delicious, this recipe delivers comfort food sophistication that’ll have everyone asking for seconds.
