You have several options, depending on the type and brand of pasta you buy. Some pasta brands sell dried Lasagna sheets pasta that doesn't need boiling first, while some do. Since in this lasagna there is quite some sauce, you should not have any issues using dried pasta without boiling first, but it's a risky business. If you want to be 100% sure you'll get a perfectly cooked lasagna, I recommend using fresh pasta or to boil the lasagna sheets before using. In general, check the packaging and follow the instructions for the best result.
