In a medium pot, add the tomatillos, jalapeños, onion, and enough water to completely cover them. Bring to a boil over medium-high heat, reduce heat to low, cover, and simmer for 8 minutes.
Using a slotted spoon, transfer the tomatillos, jalapeños, and onion to a blender. Add the cilantro, garlic, lime juice, and salt and blend until smooth. Taste and add more salt as needed.
Stack the corn tortillas on top of each other and cut them into eighths to create small triangle wedges. Line a large plate with paper towels and set aside.
Fill a large sauté pan or deep skillet with about 1-2 inches of oil and heat over medium-high heat until the temperature reaches at least 350°F. (To test, drop a small piece of tortilla in the oil. If it sizzles, it's ready.)
Working in batches, add half of the tortillas and fry for 8 minutes, stirring every minute or so, until they are crispy. Transfer them to the lined plate to drain and repeat the frying process with the remaining tortilla wedges.
Add all of the fried tortillas back to the pan and pour the salsa verde on top. Gently toss together to coat.
Carefully pour off the frying oil and wipe out the pan (or grab a clean one). Add all the fried tortillas back to the pan and pour the salsa verde over them. Gently toss together to coat.
Serve immediately and garnish with cotija cheese, cilantro, onions, and Mexican crema. Top with a fried egg if desired.
Notes
Salsa verde: Homemade salsa verde is worth it here, but a 1½ cup jar of store-bought works if you're short on time.
To bake the chips instead of frying: Spread the wedges on greased baking sheets, spray or brush with oil, and bake at 400°F for 10 to 15 minutes.
Adding an egg. A fried or sunny-side-up egg on top is the most popular way to serve these!
