Separate the clams from the clam juice. Reserve 1 cup clam juice for this recipe and set aside. Measure out remaining ingredients before beginning. Place a measuring cup in the colander you’ll use to drain the pasta, this will remind you to save some of the pasta water when that step arrives.
Start boiling water for linguine. Salt the water liberally once a boil is reached.
Meanwhile, heat olive oil in a large skillet over medium-high heat. Add the pancetta and sauté until browned and crisp, 3-4 minutes. Transfer the pancetta and any drippings from the skillet to a plate.
Turn the heat off. Add the white wine and set the heat to medium. Use a silicone spatula to "clean" the bottom and sides of the skillet. Add the shallots. Let the wine bubble and reduce by half, 6-7 minutes.
Add the clam juice, garlic, butter, and seasonings and stir to combine. Simmer over low heat while you boil the linguine.
Cook the pasta 1 minute less than al dente. (Set a timer to ensure you don’t overcook it.) Drain once cooked and reserve ½ cup pasta water.
Gradually sprinkle the Parmesan cheese into the sauce, stir it continuously as you add it. (Be sure to add it gradually, not all at once, so that it has a chance to melt as it’s added.) Add the cooked pancetta and any juices from the plate. Add the clams and stir to combine.
Add the drained linguine and the lemon juice. Use kitchen tongs to toss and combine. Simmer for 1 minute. If desired, add a little pasta water. (This adds a creamy finish and helps the pasta cling onto the sauce.) Note: the sauce is meant to be thin. The pasta will continue to absorb the sauce as it sits.
Taste and season with freshly cracked lemon pepper seasoning (or salt and freshly cracked pepper) if desired. Garnish with fresh parsley and serve with lemon wedges!
