โ๏ธ Ingredient Swap: Mascarpone vs. Sour Cream
If you donโt have mascarpone or want a slightly tangier flavor, you can use sour cream instead.
Swap Ratio: 1:1 โ replace mascarpone with the same amount of sour cream.
Flavor Notes:
- Mascarpone = ultra creamy, rich, slightly sweet, luxurious
- Sour cream = tangier, lighter, still delicious
Optional: For extra richness when using sour cream, stir in 1 tablespoon softened cream cheese โ not required, but yummy.
Tips & Tricks

- Lightly beating the eggs first prevents over-mixing later.
- Cheddar adds flavor brightness โ the combo of mozzarella + cheddar is perfect.
- Thawed hash browns layer more evenly and bake more consistently.
- Resting after baking ensures clean, even slices.
