In a medium bowl, whisk eggs, chopped chives, and coarse salt until fully combined.
Heat a nonstick skillet over medium-low heat and melt butter gently without browning.
Pour egg mixture into the skillet. Stir continuously with a spatula for about 2 minutes until soft curds form and eggs are slightly runny.
Remove skillet from heat and gently fold in ricotta cheese. Leave small pockets of ricotta for texture.
Spoon the creamy eggs over toasted sourdough bread.
Serve Easy 6-Ingredient Egg and Ricotta Toast immediately while warm.
