I made this with hot Italian turkey sausage, but you could make it with any kind of sausage.

Fennel acts as the structural anchor of this dish, transforming from a crisp, pungent bulb into a sweet, tender wedge as it absorbs the surrounding fats and liquids. When adjusting this formula for larger or smaller crowds, maintaining proper spacing on your roasting tray is critical for achieving true caramelization rather than steam-induced softening. Overcrowding the pan traps moisture released by the onions and bell peppers, which prevents the high-heat oven from developing the necessary browned edges at 450 degrees Fahrenheit. If you are doubling the quantity to feed eight guests, split the vegetables across two separate baking sheets rather than piling them high, and rotate the pans halfway through the initial 45-minute roasting window to compensate for uneven oven hotspots. Conversely, halving the recipe for two people requires scaling down the liquid components proportionally so the chicken broth and balsamic vinegar concentrate correctly without drowning the root vegetables.
Timing the insertion of the protein requires precision because fully raw sausages need enough exposure to render their interior fat and crisp their casings without drying out the root vegetables underneath. Searing the sausages lightly in a skillet beforehand kick-starts the browning process, ensuring that when they join the tender potatoes and carrots for the final uncovered 25 to 30-minute bake, they achieve a deep mahogany crust. Swapping the specified turkey links for beef or pork varieties introduces different fat volumes into the pan juices, meaning you should monitor the liquid levels closely during the final uncovered phase to prevent scorching. Basting the sausages with the pan juices at the 15-minute mark redistributes the rendered fats and balsamic vinegar, building a glossy glaze across both the meat and the fennel wedges.
Potatoes and carrots absorb liquids at predictable rates during high-heat roasting, but thicker root cuts demand extended coverage under aluminum foil to soften completely before the uncovered browning stage begins. Testing for doneness requires piercing the center of a potato chunk with a sharp knife; if resistance remains, recover the tray tightly and return it to the 450F oven for five-minute increments until fork-tender. When scaling up, ensure the ratio of extra virgin olive oil remains adequate to coat every surface uniformly, which guarantees the Italian herbs adhere properly during the initial toss.
