Fill the saucepan halfway with water and bring it to a boil over high heat. Add a pinch of salt.
Cook the pasta
Add the penne to the boiling water and let it cook for 10 to 12 min, following the package. Drain it, saving a little cooking water.
Brown the bacon
Heat the olive oil in the skillet over medium heat. Add the lardons and brown them for 3 to 4 min without adding salt.
Cook the peas
Add the frozen peas to the lardons and toss them for 2 min over medium heat. Season lightly with salt.
Make the sauce
In the bowl, beat the eggs with the crème fraîche, the rest of the Parmesan, some pepper and a pinch of salt.
Toss the pasta and sauce
Off the heat, add the drained pasta to the skillet with the lardons and peas. Add the egg mixture, stirring fast so it doesn't stick. Add a little cooking water if it gets too thick.
Tip · If the sauce gets too thick, add 2 to 3 tbsp of pasta water to loosen it without changing the flavor.
Add the butter
Off the heat, add the butter in pieces and stir until it melts and coats the pasta well.
Tip · For a creamier finish, keep some of the Parmesan to sprinkle on at the end instead of stirring it all into the sauce.
And there you go, it's readyCheck off every step to celebrate.
