• 1 (15 ounce) box refrigerated pie crusts (recommended — Pillsbury)

• 1 (1 1/3 ounce) envelope golden onion soup mix
• 1 tablespoon find dried herbs (I used Thyme, garlic salt, and parsley)
• 1⁄2 cup shredded monterey jack cheese

Equipment Needed

To get started, make sure you have these items on hand:

• Large frying pan
• 2 1/2-inch round cutter
• Mini muffin pan
• Small bowl
• Whisk

Instructions

Let’s get cooking! Follow these step-by-step instructions to create your own batch of delicious sweet onion tartlets:

1. Preheat your oven to 325 degrees F. This lower temperature allows the tartlets to bake evenly and prevents the crust from browning too quickly.

2. Melt the butter in a large frying pan over medium heat. Once melted, add the diced onions and cook until they are golden brown and caramelized, about 20-25 minutes. Stir occasionally to prevent burning and ensure even cooking. Properly caramelized onions are key to the tartlets’ signature sweetness. Set the cooked onions aside to cool slightly.

3. Unroll one pie dough at a time. Using a 2 1/2-inch round cutter, cut out as many rounds as possible (about 14 to 16). Reserve the scraps. Repeat with the second pie dough.

4. Gather together all the scrap dough and re-roll it gently. Cut out as many additional rounds as needed to make a total of 36 rounds.

5. Carefully fit each dough round into the cups of a mini muffin pan. Gently press the dough into the bottom and up the sides of each cup, making sure it is snug.

6. Place the muffin pan in the preheated oven and bake the crusts for 10 to 12 minutes. This par-baking helps to ensure that the crusts are crisp and cooked through once the filling is added. The crusts should be lightly golden. Remove the muffin pan from the oven and set aside.

7. In a small bowl, whisk together the eggs, half-and-half, golden onion soup mix, and dried herbs. Make sure the mixture is well combined and smooth. The onion soup mix adds a lovely depth of flavor and acts as a seasoning agent.

8. Divide the caramelized onions evenly among the par-baked tartlet shells, about 1/2 teaspoon per tartlet.

9. Top each tartlet with 1/2 teaspoon of shredded Monterey Jack cheese. The cheese adds a creamy, savory element that complements the sweetness of the onions.

10. Stir the egg mixture to ensure that the ingredients are evenly distributed, and then carefully fill each tartlet with the mixture. Be careful not to overfill the tartlets, as the filling will expand during baking.

11. Bake the tartlets in the preheated oven for 45 to 50 minutes, or until the filling is set and the crusts are golden brown. The tartlets are done when a knife inserted into the center comes out clean. If the crust starts to brown too quickly, you can loosely cover the muffin pan with foil during the last 15 minutes of baking.

12. Remove the tartlets from the oven and let them cool in the muffin pan for a few minutes before carefully transferring them to a wire rack to cool completely. This allows the filling to set fully and prevents the tartlets from sticking to the pan.

Expert Tips & Tricks

• Caramelizing the Onions: Don’t rush the process! Low and slow is the key to perfectly caramelized onions. Stir them frequently to prevent burning and allow their natural sugars to develop. A touch of brown sugar added during the last few minutes can enhance the sweetness.

• Pre-Baking the Crust: This step is crucial for preventing a soggy bottom. If you’re short on time, you can skip it, but the texture won’t be as ideal. Consider using pie weights or dried beans to prevent the crust from puffing up during pre-baking.

• Preventing Over-Browning: Keep an eye on the tartlets during the final stages of baking. If the crust starts to get too dark, tent the muffin pan with aluminum foil.

• Flavor Boost: For an extra layer of flavor, try adding a sprinkle of freshly grated Parmesan cheese or a dash of hot sauce to the filling.

• Make-Ahead Magic: The caramelized onions can be made a day or two in advance and stored in the refrigerator. This will save you time when you’re ready to assemble the tartlets.

Serving & Storage Suggestions

Serve these sweet onion tartlets warm or at room temperature. They make a fantastic appetizer, side dish, or even a light lunch. Garnish with a sprig of fresh thyme or parsley for an elegant presentation.

Leftover tartlets can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, simply warm them in a preheated oven at 300 degrees F for about 10 minutes, or until heated through. You can also microwave them for a quick reheat, but the crust may become slightly less crispy.

Freezing is not recommended as the texture of the crust and filling may change upon thawing.

Variations & Substitutions

• Gluten-Free: Use a gluten-free pie crust for a gluten-free version. Many store-bought options are available.
• Dairy-Free: Substitute the half-and-half with coconut milk or another plant-based milk alternative. Use a dairy-free cheese substitute or omit the cheese altogether.
• Vegetarian/Vegan: Omit the cheese to make it vegetarian. For a vegan version, in addition to dairy-free substitutes, consider using an egg replacement powder in the egg custard mixture.
• Different Onions: Try using a mix of different types of onions, such as red onions or shallots, for a more complex flavor.
• Add Veggies: Include roasted garlic, spinach, or mushrooms to the onion mixture for added nutrients and texture.

FAQs (Frequently Asked Questions):

Q: Can I use a different type of cheese?
A: Absolutely! Monterey Jack is a mild, melty cheese that works well, but you can experiment with other cheeses like Gruyere, Swiss, or even a sharp cheddar for a bolder flavor.

Q: Can I make these ahead of time?
A: Yes, you can make the tartlets a day ahead of time and store them in the refrigerator. Reheat them gently in a warm oven before serving.

Q: My crusts are browning too quickly. What should I do?
A: Tent the muffin pan loosely with aluminum foil to protect the crusts from over-browning.

Q: Can I use pre-made caramelized onions?
A: While fresh caramelized onions are best, you can use pre-made caramelized onions in a pinch. However, be sure to taste them first and adjust the seasoning as needed.

Q: What if I don’t have a mini muffin pan?
A: You can bake this as a larger tart in a regular pie dish, but adjust the baking time accordingly. It will take longer to cook through.
