Preheat oven to 450. Brush two rimmed baking sheets with oil. Arrange zucchini in a single layer on sheets and brush tops with oil; season with salt and pepper. Roast zucchini until tender and lightly golden in parts, 25 to 30 minutes, rotating sheets halfway through.
Meanwhile, in a large pot of boiling salted water, cook linguine according to package instructions. Drain pasta and return to pot. Add oil, lemon zest, and zucchini and toss to combine. Serve pasta topped with ricotta.
I made a few modifications to this. I followed the recommendation to add caramelized onions. I'm glad I did. It would have been lacking without. I also tossed the hot pasta with the ricotta and a little pasta water. It made a nice, creamy sauce. Then I added the roasted zucchini and onions and topped it all with Parmesan. I'll make it again.
i would give this recipe 3.5 stars if i could. i made a few adjustments:
- sauteed the zucchini instead of roasting it as it's 90+ degrees in NYC and we don't have central a/c
- added diced caramelized sweet onions
without the onions i think the flavor would have been a little lacking.
next time i will add more lemon zest (it kind of got lost in all of the pasta). while we're on the topic...a pound of pasta for 4 servings? it was quite a lot of food. i'd make this recipe again, though.
