What makes this dish special
Cacio e pepe is one of the most basic plates of pasta, but boy is it delicious. All you need is parmesan, butter, freshly cracked black pepper, and good quality pasta to prepare an amazing pasta. It is, without a doubt, one of my favorite Italian dishes.
Now, I don't want to butcher the classic dish since it's already pretty darn perfect. But what if I could elevate the flavors? And that's where the burnt butter enters the picture.
I recently discovered burnt butter while trying an appetizer at a restaurant. It was so delicious that I was immediately inspired to come home and create my own whipped feta with tamarind burnt butter. Now I'm looking for ways to incorporate it into as many dishes as I can and what could be more perfect than a burnt butter lemon cacio e pepe? The subtle flavors come together in this updated version of the classic to create one beautiful dish. Dare I say, I might like it just a tad more than the original.
Ingredients
- Lemon: Although traditional cacio e pepe doesn't have lemon, the acid in this recipe helps balance the richness of the burnt butter and cheese. Use fresh lemon for best results.
- Parmesan: A hard, cheese made from cow's milk with a sharp, nutty flavor. I do not recommend substituting parmesan for another cheese.
- Pecorino: A hard, salty cheese made from sheep milk with a sharp flavor. If you can't find pecorino, substitute it with an equal amount of parmesan cheese.
- Butter: Since burnt butter is one of the main flavor components of this dish, I do not recommend replacing the butter with another fat.
- Spaghetti: Spaghetti is the traditional choice for cacio e pepe but you can use another long, thin pasta such as bucatini or fettuccine.
Substitutions and variations
- Gluten-free: Use your favorite gluten-free spaghetti or long pasta.
- Spicy: If you want to add a little kick, you can add extra black pepper or a sprinkle of red chili flakes.
- Protein: Grilled chicken, crispy prosciutto, or even grilled shrimp would be great options to pair this pasta with.
Step-by-step instructions
Step 1: Make burnt butter
Burnt butter is essentially browned butter taken one step further. The butter isn't completely burned but nearly there. It should look very dark in color and smell smoky. Take your time with the butter to avoid burning it completely. Slowly heat it over low heat in a large saute pan and keep an eye on it, adjusting the heat as needed.
Recipe Tip
Use a light-colored pan to cook the browned butter to help you see the color better. If you use a black saute pan, it's harder to tell when the butter has reached the right stage.
When the butter is ready, add freshly cracked black pepper and lemon zest, stirring to combine. Now set aside the sauce while you cook the pasta.
Step 2: Cook the pasta
Since this burnt butter lemon cacio e pepe consists of only a few ingredients, it's important to use high-quality ones, including pasta. I always reach for the bronze die spaghetti because bronze-cut pasta absorbs sauce more effectively. Hence, a better pasta dish.
While the pasta is cooking, finely grate the parmesan and pecorino. Again, make sure to use high-quality cheeses. You can use only parmesan if you prefer but the mixture of the two delivers a better overall flavor.
As soon as the pasta reaches the al dente stage, drain it, reserving 1 ½ cups of the pasta water.
Step 3: Putting it all together
Then, add the pasta to the burnt butter sauce along with 1 cup of the reserved pasta water, and 2 tablespoons of butter.
Add both kinds of cheese and stir the pasta until fully combined. If you find that there is barely any sauce, add a touch more pasta water.
Season the cacio e pepe with salt and fresh lemon juice to finish. Portion the burnt butter lemon cacio e pepe into plates and finish with extra black pepper, and parmesan, if desired.
With my first bite, I knew I had done it. I found a way to keep the integrity of cacio e pepe but with a slight twist. The burnt butter adds a hint of nuttiness to the dish while the lemon balances the heaviness. It's pure heaven. And hopefully, you'll agree!
