- 1 cup Quick‑Cook Cornmeal (fine texture, for polenta)
- 3 cups Chicken Stock (low‑sodium; 2 cups for cooking polenta, 1 cup for thinning)
- 3 tablespoons Unsalted Butter (divided: 2 tbsp for polenta, 1 tbsp for sauté)
- 0.25 cup Parmesan Cheese (freshly grated)
- 1 tablespoon Olive Oil (extra‑virgin, for sautéing)
- 1 large Yellow Onion (cut into thin strips)

Instructions
Rehydrate Dried Porcini
Place the dried porcini in a bowl, cover with warm (lukewarm) water and let soak for 15 minutes. Drain, then briefly plunge the mushrooms into boiling water for 1 minute, drain again and set aside. Reserve the soaking liquid if you wish to strain it and use as mushroom broth.
Time: PT16M
Cook Polenta
In a medium saucepan bring 2 cups of chicken stock to a gentle boil. Whisk in 1 cup of quick‑cook cornmeal, reduce heat to low and stir continuously for about 50 minutes until the mixture is thick, creamy and the cornmeal is fully cooked. Stir in 2 tbsp butter and ¼ cup grated Parmesan until melted and incorporated.
Time: PT50M
Temperature: low simmer
Caramelize Onions
While the polenta cooks, melt 1 tbsp butter with 1 tbsp olive oil in a large skillet over medium heat. Add the sliced onion and cook, stirring occasionally, for 15‑20 minutes until the onions are deep golden and sweet.
Time: PT20M
Temperature: medium
Sauté Mushrooms
Add the reconstituted porcini and the sliced baby bella mushrooms to the skillet with the onions. Cook for about 15 minutes, stirring, until the mushrooms release their liquid and the mixture reduces and thickens.
Time: PT15M
Temperature: medium‑high
Add Aromatics & Deglaze
Stir in the minced garlic, chopped thyme, ½ tsp salt, 1 tbsp balsamic vinegar, ½ cup beef stock and ½ cup red wine. Increase heat to bring the mixture to a boil, then reduce to a simmer for 5 minutes, allowing the sauce to thicken slightly.
Time: PT5M
Temperature: medium‑high
Finish Polenta & Combine
Reheat the cooked polenta over low heat, adding up to 1 cup of the reserved chicken stock (or fresh stock) to achieve a creamy, pourable consistency. Spoon the hot polenta onto serving plates and top with the mushroom‑onion ragout.
Time: PT5M
Temperature: low
Garnish and Serve
Scatter a few fresh thyme leaves over each serving for color and aroma. Serve immediately while hot.
