Pro Tips

🏆 Chef Tips
  • Day-old bagels work better than fresh — they absorb more custard without getting mushy.
  • Full-fat cream cheese cubes don't fully melt — they create pockets of creamy richness throughout.
  • Everything bagel seasoning is the key flavor — buy it pre-made or mix sesame seeds, poppy seeds, dried garlic, dried onion, and salt.
  • This is fully assembled the night before — just pull from fridge and bake.

Frequently Asked Questions

Absolutely — substitute crispy bacon, cooked sausage, or extra vegetables. The everything bagel and cream cheese base is the star.
A blend of sesame seeds, poppy seeds, dried garlic, dried onion, and salt. Available at most grocery stores (Trader Joe's version is famous) or easy to make at home.
Use gluten-free bagels — the rest of the ingredients are naturally gluten-free. The texture will be slightly different but still delicious.
The center should be set (not jiggly) and a knife inserted comes out clean. The top should be golden brown.
