Frequently Asked Questions
What kind of onions should I use?
Stick with sweet onions like Vidalia or Walla Walla. They’re mild and naturally sweet when cooked, which gives this pie its signature flavor.
Can I make this ahead of time?
Yes! You can bake the whole pie, let it cool, and refrigerate it. Just reheat slices in the oven or microwave before serving. It’s great warm or at room temp.
What’s the best cracker to use for the crust?
Buttery round crackers like Ritz work perfectly. You want something that crumbles easily and has a rich, slightly salty flavor.
Can I switch up the cheese?
Absolutely. Sharp cheddar is classic, but you can try Monterey Jack, Gruyère, or even a smoked cheese if you’re feeling adventurous.
Is this a main dish or a side?
It works as both! Serve it with a salad for a light lunch or plate it up as a flavorful side dish next to grilled chicken, pork chops, or even a holiday ham.
Ingredients You’ll Need
Here’s what you’ll need to bring this savory pie to life:
- 1½ cups buttery crackers, crushed – Like Ritz or any similar brand
- 6 tbsp butter – Divided between the crust and the skillet
- 2 cups sweet onions, thinly sliced – Vidalia is a great choice
- 2 cloves garlic, minced – For just the right kick
- 1 tbsp fresh chives – Adds a touch of color and freshness
- ¾ cup whole milk – Helps create a light custard
- 2 eggs – Binds everything together
- ½ tsp salt – Adjust to taste
- ¾ cup shredded cheddar cheese – The melty topping that ties it all together
- Pinch of paprika – Adds color and a hint of flavor
- 1 tbsp chopped fresh parsley – For garnish (optional)
How to Make Sweet Onion Pie
Step 1: Prep the crust
Preheat your oven to 350°F. Mix crushed crackers with 4 tablespoons of softened butter until well combined. Press the mixture into the bottom and slightly up the sides of an 8-inch pie dish. Pop it in the fridge while you prep the filling.
Step 2: Cook the onions
In a skillet, melt the remaining 2 tablespoons of butter over medium heat. Add the sliced onions and garlic and sauté slowly—this isn’t a rush job. Let them cook for about 12 minutes until they’re soft and golden.
Step 3: Build the filling
Transfer the cooked onions to your prepared crust. In a separate bowl, whisk together the eggs, milk, salt, and chives. Pour this mixture over the onions, then sprinkle shredded cheddar cheese evenly across the top. Dust with a little paprika.
Step 4: Bake
Bake for about 35 minutes, or until the center is set and a knife comes out clean. Let it cool slightly, then garnish with fresh parsley before serving.
