The mushroom stems are useful filling ingredients, but their moisture needs attention before they return to the caps. Cooking them first gives the cheddar mixture a better chance to stay in place. This forty-five-minute recipe makes twelve stuffed cremini mushrooms, served three per person with almonds and parsley. The nuts accompany the mushrooms rather than forming a breadcrumb-style stuffing.
Cheddar & garlic stuffed mushrooms makes 4 servings, with 45 min estimated total time. View the standalone recipe page.
Prepare the caps without damaging their sides
Select twelve large cremini mushrooms with broadly similar cap sizes, about 450 g in total. Clean off debris with a damp towel or a brief rinse, then pat dry. Avoid a prolonged soak. Twist or ease out the stems carefully so the caps retain their shape and provide a useful cavity for the cooked filling.
Finely chop the removed stems, keeping their pieces small enough to sit neatly inside the caps. Brush the caps with the first 7 g olive oil and arrange cavity-side up on a rimmed tray. Leave space around them for oven heat and for any juices they release. The rim matters because mushrooms naturally give off liquid during baking.
Drive moisture from the chopped stems
Heat the remaining 7 g oil in a small skillet over medium heat and cook the stems for four to five minutes. Stir so they heat evenly and watch for their released liquid to evaporate. They should look cooked and relatively dry before you proceed. Moving a wet spoonful into a cap simply transfers that water into the filling.
Add the finely minced garlic for thirty seconds, then remove the pan from the heat. Stir in salt, pepper and half the grated cheddar. Off-heat mixing uses the warmth of the stems without cooking the cheese against the skillet for an extended period. Keep the second half of the cheddar separate for the tops so each mushroom receives both filling and finish.
Portion the filling before adding the topping
Divide the stem mixture across all twelve caps. A small spoon helps place it into the cavities without smearing it over the tray. Start with modest spoonfuls around the whole tray, then use the remaining mixture to even out the portions. Large peaks on the first mushrooms leave the others short and may slump when the cheese melts.
Scatter the reserved cheddar over the filled caps, using the mushroom surface rather than the surrounding sheet as your target. A few escaped shreds are harmless, but piles of cheese on the bare tray can darken quickly. The recipe does not call for extra cheese to conceal uneven filling, so use the measured allocation across the batch.
Bake to tender caps and a thoroughly hot center
Place the tray in the oven at 400°F/200°C and bake for fifteen to eighteen minutes. Look for tender mushrooms and cheese that bubbles and browns lightly. The caps will shrink somewhat as they cook; this is expected and is one reason not to compress them together when arranging the tray.
Check the center of the filling for 165°F/74°C, particularly in the larger mushrooms. Aim the thermometer into the filling without resting its tip against the hot metal sheet. Browned cheese alone cannot verify the center. If liquid collects around the caps, lift them out for serving rather than pouring all the tray liquid onto the plates.
Toast the almonds and rest before plating
While the mushrooms bake, toast the almonds in a dry skillet over medium-low heat for three to four minutes, moving them often. Transfer them from the hot pan and let them cool briefly before roughly chopping, if desired. The recipe also allows them to remain whole. Keep them separate from the mushrooms during the bake.
Rest the cooked mushrooms for three minutes, then serve three per person with one quarter of the almonds and parsley. Use a spoon or small spatula beneath the cap so the soft sides do not collapse under tongs. Scatter parsley over or around the mushrooms. This final green garnish and the almonds belong on the served plate, not hidden in the stem filling.
Common questions
Why does the filling seem watery?
The chopped stems may not have released and evaporated their liquid before mixing with cheese. Cook them until relatively dry, and pat the cleaned caps dry rather than soaking them.
Do the almonds go inside the mushrooms?
No. Toast them separately while the caps bake and divide them among the four plates. The actual filling is cooked mushroom stems, garlic, seasoning and half the cheddar.
