Melt butter in a large stockpot over medium heat. Cook and stir the onions, garlic, thyme, salt, and pepper in the hot butter until the onions are soft and browned, about 30 minutes.

Pour in the red wine and sherry; bring to a boil. Reduce the heat to low and simmer until you no longer smell the alcohol cooking off, about 15 minutes.

Meanwhile, preheat the oven to 350 degrees F (175 degrees C).

Sprinkle the onion mixture with flour and stir to coat; cook for 10 minutes. Pour in the broth, stir to blend in the flour, and simmer until slightly thickened, about 20 minutes.

While the soup simmers, arrange the baguette slices on a baking sheet and drizzle with olive oil. Bake the baguette slices in the preheated oven until golden brown, 12 to 14 minutes, flipping the slices halfway through. Set aside.

Set an oven rack about 8 inches from the heat source and preheat the oven's broiler.

Ladle the soup into 6 oven-proof crocks, filling them about 3/4 full. Place 1 or 2 toasted baguette slices over each serving of soup, then top each with a Swiss cheese slice and a provolone slice. Carefully set the filled crocks on a sturdy baking sheet.

Cook the soup under the preheated broiler until the cheese is browned and bubbly, 3 to 4 minutes.

How easyChef Pro Scores This Recipe
easyChef Pro gives every recipe a health score from 0 to 100, built from more than 30 nutritional parameters including nutrient density, energy density and glycemic impact. It calculates rather than estimates, so the same recipe returns the same score every time.
The number is traceable. You can see exactly which nutrient moved it, so a dish scoring 78 might show fiber pushing it up while sodium pulls it down, alongside the NOVA processing level of each ingredient.
Your health goal changes the calculation itself, not just a filter. easyChef Pro applies clinically derived weighting across six health dimensions, which is why the same dish can score well for one goal and poorly for another.
Swap an ingredient or change the serving size and that math changes with it. Scoring your own version is the only way to see what your kitchen actually produces.
