I will present recent results from SOFIA/FORCAST imaging of massive young stellar objects (YSOs) in three star-forming HII regions of the Large Magellanic Cloud. We use photometry at 25.3–37.1 μm to constrain model fits to near/mid-infrared SEDs and determine luminosities, ages, and dust content of the embedded YSOs and their local environments. By placing observed sources on mid-infrared color–magnitude and color–color diagrams, we analyze their dust properties and consider their evolutionary status. Since each object in the FORCAST images has an obvious bright near-infrared counterpart in Spitzer images, we do not find any evidence for new, very cool, previously undiscovered Class 0 YSOs. A brief history of the LMC complexes and their relative ages will also be discussed.
