- Unroll the crescent dough sheet and press the perforations together to form a solid rectangle.

- In the same pan, sauté chopped onion until translucent.
- In a bowl, combine sour cream, egg yolks, grated Parmesan cheese, salt, and pepper.
- Spread the sour cream mixture evenly over the dough rectangle.
- Sprinkle chopped bacon, cooked onion, and chopped rosemary over the top.
- Bake in the preheated oven for 20 minutes or until golden brown.
- Slice and serve warm.
Tips & Substitutions
For a twist, try using goat cheese instead of Parmesan for a tangy flavor. If you prefer a lighter option, substitute Greek yogurt for sour cream. Ensure the bacon is well-cooked for maximum crispiness; you can also use turkey bacon as a healthier alternative. Fresh herbs elevate the dish, so consider adding thyme or chives alongside the rosemary.
Serving Suggestions
Serve the tart warm as a delightful appetizer, or pair it with a fresh salad for a light meal. It also makes a great addition to a brunch spread, alongside dishes like Mom'S Deviled Eggs or a fruit platter. For a heartier option, consider serving with roasted vegetables.
Storage & Reheating
Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place slices in a preheated oven at 350°F (175°C) for about 10 minutes or until warmed through. You can also microwave individual servings for about 30 seconds, but the oven will keep the crust crisp.

Frequently Asked Questions
Can I make this tart in advance?
Yes, you can prepare the tart up to the baking step. Cover it tightly and refrigerate for up to 24 hours. When ready to bake, simply preheat the oven and bake as directed. This allows the flavors to meld beautifully while saving you time on the day of serving.
Can I freeze the bacon onion tart?
Freezing is possible, but it's best to do so before baking. Wrap the assembled but unbaked tart tightly in plastic wrap and then foil. Freeze for up to 2 months. When ready to enjoy, thaw in the refrigerator overnight and bake as directed.
What can I substitute for sour cream?
Greek yogurt is an excellent substitute for sour cream, providing a similar texture and tangy flavor. You can also use crème fraîche for a richer taste. If you want a dairy-free option, try using a cashew cream or coconut yogurt, adjusting the seasoning as necessary.
